Enum ImageDataFormat 

#[non_exhaustive]
pub enum ImageDataFormat {
    Bgra8 {
        size: Size2D<Px, Px>,
        density: Option<Size2D<PxDensity, PxDensity>>,
    },
    A8 {
        size: Size2D<Px, Px>,
    },
    FileExtension(Txt),
    MimeType(Txt),
    Unknown,
}

Format of the image bytes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bgra8

Decoded BGRA8.

This is the internal image format, it indicates the image data is already decoded and color managed (to sRGB).

Fields

size: Size2D<Px, Px>

Size in pixels.

density: Option<Size2D<PxDensity, PxDensity>>

Pixel density of the image.

A8

Decoded A8.

This is the internal mask format it indicates the mask data is already decoded.

Fields

size: Size2D<Px, Px>

Size in pixels.

FileExtension(Txt)

The image is encoded.

This file extension maybe identifies the format. Fallback to Unknown handling if the file extension is unknown or the file header does not match.

MimeType(Txt)

The image is encoded.

This MIME type maybe identifies the format. Fallback to Unknown handling if the file extension is unknown or the file header does not match.

Unknown

The image is encoded.

A decoder will be selected using the “magic number” at the start of the bytes buffer.

Trait Implementations

impl Clone for ImageDataFormat

fn clone(&self) -> ImageDataFormat

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<ImageDataFormat, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&str> for ImageDataFormat

fn from(ext_or_mime: &str) -> ImageDataFormat

Converts to this type from the input type.

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

fn from(bgra8_size: Size2D<Px, Px>) -> ImageDataFormat

Converts to this type from the input type.

impl From<Txt> for ImageDataFormat

fn from(ext_or_mime: Txt) -> ImageDataFormat

Converts to this type from the input type.

impl Hash for ImageDataFormat

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

where H: Hasher,

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: &ImageDataFormat) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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 as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
