    },

}

Format of the image bytes.

Variants

Bgra8

Decoded BGRA8.

This is the internal image format, it indicates the image data is already decoded and must only be entered into the cache.

Fields

size: PxSize

Size in pixels.

ppi: Option<ImagePpi>

Pixels-per-inch of the image.

A8

Decoded A8.

This is the internal mask format it indicates the mask data is already decoded and must only be entered into the cache.

Fields

size: PxSize

Size in pixels.

FileExtension(Txt)

The image is encoded, a file extension that maybe identifies the format is known.

MimeType(Txt)

The image is encoded, MIME type that maybe identifies the format is known.

Unknown

The image is encoded, a decoder will be selected using the “magic number” on the beginning of the bytes buffer.

Trait Implementations

impl Clone for ImageDataFormat

fn clone(&self) -> ImageDataFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageDataFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ImageDataFormat

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for ImageDataFormat

fn from(ext_or_mime: &str) -> Self

Converts to this type from the input type.

impl From<Size2D<Px, Px>> for ImageDataFormat

fn from(bgra8_size: PxSize) -> Self

Converts to this type from the input type.

impl From<Txt> for ImageDataFormat

fn from(ext_or_mime: Txt) -> Self

Converts to this type from the input type.

impl Hash for ImageDataFormat

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ImageDataFormat

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ImageDataFormat

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
