func CutLast(s, sep string) (before, after string, found bool)

CutLast is strings.Cut, but cutting at the last occurrence of sep rather than the first.

func CutPrefix(s, prefix string) (after string, found bool)

CutPrefix behaves like strings.Cut, but only cuts a prefix, not anywhere in the string.

CutSuffix behaves like strings.Cut, but only cuts a suffix, not anywhere in the string.

func CutTwice(s, sep1, sep2 string) (before, between, after string, found bool)

type CRLFToLF struct{}

CRLFToLF is a transform.Transformer that converts all occurrences of "\r\n" to "\n", leaving lone '\r' (not followed by '\n') untouched.

func (CRLFToLF) Reset()

Reset implements transform.Transformer. No state to clear.

func (CRLFToLF) Transform(dst, src []byte, atEOF bool) (nDst, nSrc int, err error)

Transform converts CRLF to LF. Implements transform.Transformer. It's careful about chunk boundaries and dst capacity.
