Struct ImageFormatCapability 

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

Capabilities of an ImageFormat implementation.

Note that DECODE capability is omitted because the view-process can always decode formats.

Implementations

impl ImageFormatCapability

pub const ENCODE: ImageFormatCapability

View-process can encode images in this format.

pub const DECODE_ENTRIES: ImageFormatCapability

View-process can decode multiple containers of the format with multiple image entries.

pub const ENCODE_ENTRIES: ImageFormatCapability

View-process can encode multiple images into a single container of the format.

pub const DECODE_PROGRESSIVE: ImageFormatCapability

View-process can decode pixels as they are received.

Note that the view-process can always handle progressive data by accumulating it and then decoding. The decoder can also decode the metadata before receiving all data, that does not count as progressive decoding either.

impl ImageFormatCapability

pub const fn empty() -> ImageFormatCapability

Get a flags value with all bits unset.

pub const fn all() -> ImageFormatCapability

Get a flags value with all known bits set.

pub const fn bits(&self) -> u32

Get the underlying bits value.

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

pub const fn from_bits(bits: u32) -> Option<ImageFormatCapability>

Convert from a bits value.

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

pub const fn from_bits_truncate(bits: u32) -> ImageFormatCapability

Convert from a bits value, unsetting any unknown bits.

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

Convert from a bits value exactly.

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

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 const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

pub const fn intersects(&self, other: ImageFormatCapability) -> bool

Whether any set bits in a source flags value are also set in a target flags value.

pub const fn contains(&self, other: ImageFormatCapability) -> bool

Whether all set bits in a source flags value are also set in a target flags value.

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

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

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

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: ImageFormatCapability)

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

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

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

pub const fn intersection( self, other: ImageFormatCapability, ) -> ImageFormatCapability

The bitwise and (&) of the bits in two flags values.

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

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

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

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: ImageFormatCapability, ) -> ImageFormatCapability

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

pub const fn complement(self) -> ImageFormatCapability

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

impl ImageFormatCapability

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

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<ImageFormatCapability>

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.
