Struct StreamingAssetReader 

pub struct StreamingAssetReader<R> { /* private fields */ }

A BundledAssetReader over any byte stream.

Every backend that streams an asset ends at the same loop: fill a chunk, stop at the end, name the asset rather than its resolved location when the read fails. What differs is only what was opened — a file beside the executable, a file in an application bundle, a span of an Android package, or bytes already in hand — and whether the asset ends where its stream does. The loop lives here once; a backend supplies the stream and, when its asset is a span of something larger, how many bytes of it are its own.

Implementations

impl<R: Read + Send> StreamingAssetReader<R>

pub fn new(path: impl Into<String>, source: R) -> Self

A reader over a stream whose end is the asset’s end.

pub fn with_length(path: impl Into<String>, source: R, len: u64) -> Self

A reader over len bytes of a stream that continues past the asset — an Android package’s file descriptor addresses the whole package, so the asset’s end is a count rather than end of file.

Trait Implementations

impl<R: Read + Send> BundledAssetReader for StreamingAssetReader<R>

fn read_chunk(&mut self) -> Result<Option<Vec<u8>>, BundledAssetError>

Reads the next chunk, or None at end of asset.
