A file representation for the web platform

Implementations

impl WebFileData

pub fn new(file: File, reader: FileReader) -> Self

Create a new WebFileData from a web_sys::File

Trait Implementations

impl Clone for WebFileData

fn clone(&self) -> WebFileData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl NativeFileData for WebFileData

fn byte_stream( &self, ) -> Pin<Box<dyn Stream<Item = Result<Bytes, CapturedError>> + Send + 'static>>

we’d like to use blob to readable stream here, but we cannot.

We just read the entire file into memory and return it as a single chunk. This is not super great, especially given the wasm <-> js boundary duplication cost.

For more efficient streaming of byte data, consider using the dedicated FileStream type which goes directly from File to fetch request body without going through Rust.

We should maybe update these APIs to use our own custom ByteBuffer type to avoid going through Vec<u8>?
