import { type ReaderSync } from "https://deno.land/std@0.220.1/io/iterate_reader.ts";
An abstract interface which when implemented provides an interface to read bytes into an array buffer synchronously.
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() returns 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 returns what is
available instead of waiting for more.
When readSync() encounters end-of-file condition, it returns EOF
(null).
When readSync() encounters an error, it throws 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.
