Copy copies from src to dst until either EOF is reached on src or an error occurs.

CopyN copies n bytes (or until an error) from src to dst.

LimitReader returns a Reader that reads from r but stops with EOF after n bytes.

NewSectionReader returns a SectionReader that reads from r starting at offset off and stops with EOF after n bytes.

ReadAtLeastCustom reads from r into buf until it has read at least min bytes.

ReadFull reads exactly len(buf) bytes from r into buf.

TeeReader returns a Reader that writes to w what it reads from r.

WriteString writes the contents of the string s to w, which accepts an array of bytes.

EOF is the error returned by Read when no more input is available.

ErrNoProgress is returned by some clients of an io.Reader when many calls to Read have failed to return any data or error, usually the sign of a broken io.Reader implementation.

ErrShortBuffer means that a read required a longer buffer than was provided.

ErrShortWrite means that a write accepted fewer bytes than requested but failed to return an explicit error.

ErrUnexpectedEOF means that EOF was encountered in the middle of reading a fixed-size block or data structure.

A LimitedReader reads from R but limits the amount of data returned to just N bytes.

SectionReader implements Read, Seek, and ReadAt on a section of an underlying ReaderAt.
