bufcp

Documentation

Overview

Package bufcp provides functions for copying data from a reader to a writer with explicit control over buffer size and flushing of buffered data after each write. This package is particularly useful when working with the CreateWriteStream function of FastHTTP's Response, which returns a bufio.Writer. By flushing the writer after each write, data is sent to the client immediately, allowing the server to start sending large responses without having to buffer them entirely in memory first. This can help manage memory usage when working with large files or streams of data.

Functions

func Copy

func Copy(dst *bufio.Writer, src io.Reader, bufSize int) (int64, error)

Copy copies from src to dst until either EOF is reached on src or an error occurs. It uses a buffer of size bufSize and flushes the buffer after each writing.

func CopyN

func CopyN(dst *bufio.Writer, src io.Reader, n int64, bufSize int) (int64, error)

CopyN copies n bytes (or until an error occurs) from src to dst. It uses a buffer of size bufSize and flushes the buffer after each writing.
