import { type Deno } from "https://deno.land/x/ayonli_jsext@v0.9.72/lib.deno.d.ts";
const { Reader } = Deno;
An abstract interface which when implemented provides an interface to read bytes into an array buffer asynchronously.
Methods
Reads up to p.byteLength bytes into p. It resolves to the number of
bytes read (0 < n <= p.byteLength) and rejects if any error
encountered. Even if read() resolves to n < p.byteLength, it may
use all of p as scratch space during the call. If some data is
available but not p.byteLength bytes, read() conventionally resolves
to what is available instead of waiting for more.
When read() encounters end-of-file condition, it resolves to EOF
(null).
When read() encounters an error, it rejects with an error.
Callers should always process the n > 0 bytes returned before
considering the EOF (null). Doing so correctly handles I/O errors that
happen after reading some bytes and also both of the allowed EOF
behaviors.
Implementations should not retain a reference to p.
Use
itereateReader
from
std/streams/iterate_reader.ts
to turn a Reader into an AsyncIterator.
