    The caller of the bitflags! macro can chose to allow or +disallow extra bits for their bitflags type.

    +

    The caller of from_bits_unchecked() has to ensure that +all bits correspond to a defined flag or that extra bits +are valid for this bitflags type.

    +

    Returns true if no flags are currently stored.

    +

    Returns true if all flags are currently set.

    +

    Returns true if there are flags common to both self and other.

    +

    Returns true if all of the flags in other are contained within self.

    +

    Inserts the specified flags in-place.

    +

    Removes the specified flags in-place.

    +

    Toggles the specified flags in-place.

    +

    Inserts or removes the specified flags depending on the passed value.

    +

    Returns the intersection between the flags in self and +other.

    +

    Specifically, the returned set contains only the flags which are +present in both self and other.

    +

    This is equivalent to using the & operator (e.g. +ops::BitAnd), as in flags & other.

    +

    Returns the union of between the flags in self and other.

    +

    Specifically, the returned set contains all flags which are +present in either self or other, including any which are +present in both (see Self::symmetric_difference if that +is undesirable).

    +

    This is equivalent to using the | operator (e.g. +ops::BitOr), as in flags | other.

    +

    Returns the difference between the flags in self and other.

    +

    Specifically, the returned set contains all flags present in +self, except for the ones present in other.

    +

    It is also conceptually equivalent to the “bit-clear” operation: +flags & !other (and this syntax is also supported).

    +

    This is equivalent to using the - operator (e.g. +ops::Sub), as in flags - other.

    +

    Returns the symmetric difference between the flags +in self and other.

    +

    Specifically, the returned set contains the flags present which +are present in self or other, but that are not present in +both. Equivalently, it contains the flags present in exactly +one of the sets self and other.

    +

    This is equivalent to using the ^ operator (e.g. +ops::BitXor), as in flags ^ other.

    +

    Returns the complement of this set of flags.

    +

    Specifically, the returned set contains all the flags which are +not set in self, but which are allowed for this type.

    +

    Alternatively, it can be thought of as the set difference +between Self::all() and self (e.g. Self::all() - self)

    +

    This is equivalent to using the ! operator (e.g. +ops::Not), as in !flags.

    +

    Do not check validity for simplicity +Return (readable, writable)

    Implementations

    Returns an empty set of flags.

    +

    Returns the set containing all flags.

    +

    Returns the raw value of the flags currently stored.

    +

    Convert from underlying bit representation, unless that +representation contains bits that do not correspond to a flag.

    +

    Convert from underlying bit representation, dropping any bits +that do not correspond to flags.

    +

    Convert from underlying bit representation, preserving all +bits (even those not corresponding to a defined flag).

    +
    Safety
    +

    The caller of the bitflags! macro can chose to allow or +disallow extra bits for their bitflags type.

    +

    The caller of from_bits_unchecked() has to ensure that +all bits correspond to a defined flag or that extra bits +are valid for this bitflags type.

    +

    Returns true if no flags are currently stored.

    +

    Returns true if all flags are currently set.

    +

    Returns true if there are flags common to both self and other.

    +

    Returns true if all of the flags in other are contained within self.

    +

    Inserts the specified flags in-place.

    +

    Removes the specified flags in-place.

    +

    Toggles the specified flags in-place.

    +

    Inserts or removes the specified flags depending on the passed value.

    +

    Returns the intersection between the flags in self and +other.

    +

    Specifically, the returned set contains only the flags which are +present in both self and other.

    +

    This is equivalent to using the & operator (e.g. +ops::BitAnd), as in flags & other.

    +

    Returns the union of between the flags in self and other.

    +

    Specifically, the returned set contains all flags which are +present in either self or other, including any which are +present in both (see Self::symmetric_difference if that +is undesirable).

    +

    This is equivalent to using the | operator (e.g. +ops::BitOr), as in flags | other.

    +

    Returns the difference between the flags in self and other.

    +

    Specifically, the returned set contains all flags present in +self, except for the ones present in other.

    +

    It is also conceptually equivalent to the “bit-clear” operation: +flags & !other (and this syntax is also supported).

    +

    This is equivalent to using the - operator (e.g. +ops::Sub), as in flags - other.

    +

    Returns the symmetric difference between the flags +in self and other.

    +

    Specifically, the returned set contains the flags present which +are present in self or other, but that are not present in +both. Equivalently, it contains the flags present in exactly +one of the sets self and other.

    +

    This is equivalent to using the ^ operator (e.g. +ops::BitXor), as in flags ^ other.

    +

    Returns the complement of this set of flags.

    +

    Specifically, the returned set contains all the flags which are +not set in self, but which are allowed for this type.

    +

    Alternatively, it can be thought of as the set difference +between Self::all() and self (e.g. Self::all() - self)

    +

    This is equivalent to using the ! operator (e.g. +ops::Not), as in !flags.

    Implementations

    Returns an empty set of flags.

    +

    Returns the set containing all flags.

    +

    Returns the raw value of the flags currently stored.

    +

    Convert from underlying bit representation, unless that +representation contains bits that do not correspond to a flag.

    +

    Convert from underlying bit representation, dropping any bits +that do not correspond to flags.

    +

    Convert from underlying bit representation, preserving all +bits (even those not corresponding to a defined flag).

    +
    Safety
    +

    The caller of the bitflags! macro can chose to allow or +disallow extra bits for their bitflags type.

    +

    The caller of from_bits_unchecked() has to ensure that +all bits correspond to a defined flag or that extra bits +are valid for this bitflags type.

    +

    Returns true if no flags are currently stored.

    +

    Returns true if all flags are currently set.

    +

    Returns true if there are flags common to both self and other.

    +

    Returns true if all of the flags in other are contained within self.

    +

    Inserts the specified flags in-place.

    +

    Removes the specified flags in-place.

    +

    Toggles the specified flags in-place.

    +

    Inserts or removes the specified flags depending on the passed value.

    +

    Returns the intersection between the flags in self and +other.

    +

    Specifically, the returned set contains only the flags which are +present in both self and other.

    +

    This is equivalent to using the & operator (e.g. +ops::BitAnd), as in flags & other.

    +

    Returns the union of between the flags in self and other.

    +

    Specifically, the returned set contains all flags which are +present in either self or other, including any which are +present in both (see Self::symmetric_difference if that +is undesirable).

    +

    This is equivalent to using the | operator (e.g. +ops::BitOr), as in flags | other.

    +

    Returns the difference between the flags in self and other.

    +

    Specifically, the returned set contains all flags present in +self, except for the ones present in other.

    +

    It is also conceptually equivalent to the “bit-clear” operation: +flags & !other (and this syntax is also supported).

    +

    This is equivalent to using the - operator (e.g. +ops::Sub), as in flags - other.

    +

    Returns the symmetric difference between the flags +in self and other.

    +

    Specifically, the returned set contains the flags present which +are present in self or other, but that are not present in +both. Equivalently, it contains the flags present in exactly +one of the sets self and other.

    +

    This is equivalent to using the ^ operator (e.g. +ops::BitXor), as in flags ^ other.

    +

    Returns the complement of this set of flags.

    +

    Specifically, the returned set contains all the flags which are +not set in self, but which are allowed for this type.

    +

    Alternatively, it can be thought of as the set difference +between Self::all() and self (e.g. Self::all() - self)

    +

    This is equivalent to using the ! operator (e.g. +ops::Not), as in !flags.
