Struct MarkerTraits 

pub struct MarkerTraits(/* private fields */);

Bitflags for common marker traits that a type may implement

Note: facet is not able to see negative impls, so it might mistakenly think a struct S is Send because all its fields are, ignoring that there is an impl !Send for S.

Similarly, it might think a struct S is !Send just because one of the fields is an UnsafeCell (which is !Send), ignoring that there is an unsafe impl Send for S.

The reason facet’s determination of Send or !Send is based on fields is because structs can be generic, in which case our specialization trick does not work.

Convert from a bits value.

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

pub const fn from_bits_retain(bits: u8) -> Self

Convert from a bits value exactly.

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

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

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

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

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: Self)

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

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

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

pub const fn union(self, other: Self) -> Self

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

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

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: Self) -> Self

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

pub const fn complement(self) -> Self

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

impl MarkerTraits

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

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<MarkerTraits>

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.
