Readers
The io
package specifies the io.Reader
interface,
which represents the read end of a stream of data.
The Go standard library contains many implementations of this interface, including files, network connections, compressors, ciphers, and others.
The io.Reader
interface has a Read
method:
func (T) Read(b []byte) (n int, err error)
Read
populates the given byte slice with data and returns the number of bytes
populated and an error value. It returns an io.EOF
error when the stream
ends.
The example code creates a
strings.Reader
and consumes its output 8 bytes at a time.
