Methods
read(p: Uint8Array): Promise<number | EOF>
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 read() encounters end-of-file condition, it returns EOF symbol.
When read() encounters an error, it rejects with an error.
Callers should always process the n > 0 bytes returned before
considering the EOF. Doing so correctly handles I/O errors that happen
after reading some bytes and also both of the allowed EOF behaviors.
Implementations must not retain p.
