Struct OneBitInfo 

pub struct OneBitInfo;

A one-bit picture in a PNG’s place, read for the size of the PNG it was made from (one-bit), which ImageInfo::checked must allow. It claims no extension: it is found by its magic bytes at a PNG’s path, so a .1bit file beside a PNG (a touched-up picture a build reads) is not an image of its own.

Trait Implementations

impl Clone for OneBitInfo

fn clone(&self) -> OneBitInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OneBitInfo

impl Debug for OneBitInfo

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

Formats the value using the given formatter.

impl Default for OneBitInfo

fn default() -> OneBitInfo

Returns the “default value” for a type.

impl Eq for OneBitInfo

impl Format for OneBitInfo

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 OneBitInfo

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

Equality operator ==.

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

Inequality operator !=.
