Convert from a bits value.

This method will return None if any unknown bits are set.

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<WriteMask>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub fn insert(&mut self, other: WriteMask)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: WriteMask)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: WriteMask)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: WriteMask, value: bool)

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: WriteMask) -> WriteMask

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: WriteMask) -> WriteMask

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> WriteMask

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl WriteMask

pub const fn iter(&self) -> Iter<WriteMask>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<WriteMask>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
