interface Deno.Writer


write(p: Uint8Array): Promise<number>

Writes p.byteLength bytes from p to the underlying data stream. It resolves to the number of bytes written from p (0 <= n <= p.byteLength) or reject with the error encountered that caused the write to stop early. write() must reject with a non-null error if would resolve to n < p.byteLength. write() must not modify the slice data, even temporarily.

Implementations should not retain a reference to p.
