Struct neo_mime::Value

pub struct Value<'a> { /* fields omitted */ }

A parameter value section of a MediaType or MediaRange.

Except for the charset parameter, parameters are compared case-sensitive.

Implementations

impl<'a> Value<'a>

pub fn as_str_repr(&self) -> &'a str

Returns the underlying representation.

The underlying representation differs from the content, as it can contain quotes surrounding the content and quoted-pairs, even if non of them are necessary to represent the content.

For example the representation r#""a\"\ b""# corresponds to the content r#""a" b"#. Another semantically equivalent (i.e. with the same content) representation is r#""a\" b""

Example

let mime = r#"text/plain; param="abc def""#.parse::<neo_mime::MediaType>().unwrap();
let param = mime.param("param").unwrap();
assert_eq!(param.as_str_repr(), r#""abc def""#);

pub fn to_content(&self) -> Cow<'a, str>

Returns the content of this instance.

It differs to the representation in that it will remove the quotation marks from the quoted string and will “unquote” quoted pairs.

If the underlying representation is a quoted string containing quoted-pairs Cow::Owned is returned.

If the underlying representation is a quoted-string without quoted-pairs Cow::Borrowed is returned as normal str slicing can be used to strip the surrounding double quoted.

If the underlying representation is not a quoted-string Cow::Borrowed is returned, too.

Example

let raw_mime = r#"text/plain; p1="char is \""; p2="simple"; p3=simple2"#;
let mime = raw_mime.parse::<neo_mime::MediaType>().unwrap();

let param1 = mime.param("p1").unwrap();
let expected = r#"char is ""#;
assert_eq!(param1.to_content(), expected);

let param2 = mime.param("p2").unwrap();
assert_eq!(param2.to_content(), "simple");

let param3 = mime.param("p3").unwrap();
assert_eq!(param3.to_content(), "simple2");
