with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.

result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

[![crates.io](https://img.shields.io/crates/v/mime.svg)](https://crates.io/crates/mime)
[![docs.rs](https://docs.rs/mime/badge.svg)](https://docs.rs/mime)
Support MIME (Media Types) as strong types in Rust.
[Documentation](https://docs.rs/mime)
## Usage
```rust
extern crate mime;
// common types are constants
let text = mime::TEXT_PLAIN;
// deconstruct Mimes to match on them
match (text.type_(), text.subtype()) {
(mime::TEXT, mime::PLAIN) => {
// plain text!
},
(mime::TEXT, _) => {
// structured text!
},
_ => {
// not text!
}
}

// From [RFC6838](http://tools.ietf.org/html/rfc6838#section-4.2):
//
// > All registered media types MUST be assigned top-level type and
// > subtype names. The combination of these names serves to uniquely
// > identify the media type, and the subtype name facet (or the absence
// > of one) identifies the registration tree. Both top-level type and
// > subtype names are case-insensitive.
// >
// > Type and subtype names MUST conform to the following ABNF:
// >
// > type-name = restricted-name
// > subtype-name = restricted-name
// >
// > restricted-name = restricted-name-first *126restricted-name-chars
// > restricted-name-first = ALPHA / DIGIT
// > restricted-name-chars = ALPHA / DIGIT / "!" / "#" /
// > "$" / "&" / "-" / "^" / "_"
// > restricted-name-chars =/ "." ; Characters before first dot always
// > ; specify a facet name
// > restricted-name-chars =/ "+" ; Characters after last plus always
// > ; specify a structured syntax suffix
// However, [HTTP](https://tools.ietf.org/html/rfc7231#section-3.1.1.1):
//
// > media-type = type "/" subtype *( OWS ";" OWS parameter )
// > type = token
// > subtype = token
// > parameter = token "=" ( token / quoted-string )
//
// Where token is defined as:
//
// > token = 1*tchar
// > tchar = "!" / "#" / "$" / "%" / "&" / "'" / "*" / "+" / "-" / "." /
// > "^" / "_" / "`" / "|" / "~" / DIGIT / ALPHA
