class BufWriter
implements Writer

import { BufWriter } from "https://deno.land/std@0.197.0/io/buf_writer.ts";
BufWriter implements buffering for an deno.Writer object. If an error occurs writing to a Writer, no more data will be accepted and all subsequent writes, and flush(), will return the error. After all data has been written, the client should call the flush() method to guarantee all data has been forwarded to the underlying deno.Writer.

BufWriter(writer: Writer, size?: number)Methods
flush()
Flush writes any buffered data to the underlying io.Writer.
Discards any unflushed buffered data, clears any error, and resets buffer to write its output to w.
write(data: Uint8Array): Promise<number>
Writes the contents of data into the buffer. If the contents won't fully
fit into the buffer, those bytes that are copied into the buffer will be flushed
to the writer and the remaining bytes are then copied into the now empty buffer.
