Struct PngInfo 

pub struct PngInfo;

PNG read for its size (png, .png): only its header, never its pixels. The size must be one ImageInfo::checked allows.

Trait Implementations

impl Clone for PngInfo

fn clone(&self) -> PngInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PngInfo

impl Debug for PngInfo

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

Formats the value using the given formatter.

impl Default for PngInfo

fn default() -> PngInfo

Returns the “default value” for a type.

impl Eq for PngInfo

impl Format for PngInfo

type Asset = ImageInfo

The kind it reads.

fn id(&self) -> &'static str

Stable id, e.g. "png", "tiled-tmx", "yarn": one per format of a kind.

fn extensions(&self) -> &'static [&'static str]

File extensions this format claims, lowercase, without the dot. A format that only stands in another’s place (a one-bit picture at a PNG’s path) claims none and is found by sniff.

fn sniff(&self, bytes: &[u8]) -> bool

True if these bytes look like this format (magic bytes); false when the format has none.

fn max_bytes(&self) -> usize

The most bytes it reads: a bigger file is refused before decode sees it. DEFAULT_MAX_BYTES unless the format says.

fn decode( &self, file: &AssetPath, bytes: &[u8], _cx: &DecodeCx<'_>, ) -> Result<ImageInfo, Vec<ContentError>>

Every problem found, each with file and place; never a panic.

impl PartialEq for PngInfo

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

Equality operator ==.

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

Inequality operator !=.
