impl MemoryFormatSelection

pub const fn empty() -> MemoryFormatSelection

Get a flags value with all bits unset.

pub const fn all() -> MemoryFormatSelection

Get a flags value with all known bits set.

Convert from a bits value.

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

pub const fn from_bits_retain(bits: u32) -> MemoryFormatSelection

Convert from a bits value exactly.

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

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: MemoryFormatSelection)

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

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

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: MemoryFormatSelection)

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

pub fn set(&mut self, other: MemoryFormatSelection, 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: MemoryFormatSelection, ) -> MemoryFormatSelection

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.

pub const fn complement(self) -> MemoryFormatSelection

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

impl MemoryFormatSelection

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

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<MemoryFormatSelection>

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.

impl MemoryFormatSelection

pub fn memory_formats(self) -> Vec<MemoryFormat>

pub fn best_format_for(self, src: MemoryFormat) -> Option<MemoryFormat>

Select the best contained format to represent src

The function returns None if no formats are selected.
