DefaultType is the type used when we can't know/guess the filetype.

Functions

func ByExtension

func ByExtension(ext string) string

ByExtension calls mime.TypeByExtension, and removes optional parameters, to keep only the type and subtype. Example: text/html

func FromReader

func FromReader(r io.Reader) (string, io.Reader)

FromReader takes a reader, sniffs the beginning of it, and returns the mime-type (no charset) and a new reader that's the concatenation of the bytes sniffed and the remaining reader.

func Match

func Match(buf []byte) string

Match returns the mime-type (no charset) if it can guess from the first bytes, or the default content-type else.
