impl Fdflags

source

pub const fn empty() -> Self

Get a flags value with all bits unset.

source

pub const fn all() -> Self

Get a flags value with all known bits set.

source

pub const fn bits(&self) -> u16

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

source

pub const fn from_bits(bits: u16) -> Option<Self>

Convert from a bits value.

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

source

pub const fn from_bits_truncate(bits: u16) -> Self

Convert from a bits value, unsetting any unknown bits.

source

pub const fn from_bits_retain(bits: u16) -> Self

Convert from a bits value exactly.

source

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

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

source

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

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

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

source

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

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

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

source

pub const fn complement(self) -> Self

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

source§

impl Fdflags

source

source

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

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.
