Exported Values


	 func AddExtensionType(ext, typ string) error
		AddExtensionType sets the MIME type associated with
		the extension ext to typ. The extension should begin with
		a leading dot, as in ".html".


	const BEncoding WordEncoder = 98
		BEncoding represents Base64 encoding scheme as defined by RFC 2045.


	  var ErrInvalidMediaParameter error
		ErrInvalidMediaParameter is returned by ParseMediaType if
		the media type value was found but there was an error parsing
		the optional parameters


	 func ExtensionsByType(typ string) ([]string, error)
		ExtensionsByType returns the extensions known to be associated with the MIME
		type typ. The returned extensions will each begin with a leading dot, as in
		".html". When typ has no associated extensions, ExtensionsByType returns an
		nil slice.


	 func FormatMediaType(t string, param map[string]string) string
		FormatMediaType serializes mediatype t and the parameters
		param as a media type conforming to RFC 2045 and RFC 2616.
		The type and parameter names are written in lower-case.
		When any of the arguments result in a standard violation then
		FormatMediaType returns the empty string.


	 func ParseMediaType(v string) (mediatype string, params map[string]string, err error)
		ParseMediaType parses a media type value and any optional
		parameters, per RFC 1521.  Media types are the values in
		Content-Type and Content-Disposition headers (RFC 2183).
		On success, ParseMediaType returns the media type converted
		to lowercase and trimmed of white space and a non-nil map.
		If there is an error parsing the optional parameter,
		the media type will be returned along with the error
		ErrInvalidMediaParameter.
		The returned map, params, maps from the lowercase
		attribute to the attribute value with its case preserved.


	const QEncoding WordEncoder = 113
		QEncoding represents the Q-encoding scheme as defined by RFC 2047.


	 func TypeByExtension(ext string) string
		TypeByExtension returns the MIME type associated with the file extension ext.
		The extension ext should begin with a leading dot, as in ".html".
		When ext has no associated type, TypeByExtension returns "".

		Extensions are looked up first case-sensitively, then case-insensitively.

		The built-in table is small but on unix it is augmented by the local
		system's mime.types file(s) if available under one or more of these
		names:

		  /etc/mime.types
		  /etc/apache2/mime.types
		  /etc/apache/mime.types

		On Windows, MIME types are extracted from the registry.

		Text types have the charset parameter set to "utf-8" by default.
