Implementations

impl<'a> MediaType<'a>

pub const fn new(ty: Name<'a>, subty: Name<'a>) -> Self

Constructs a MediaType from a top-level type and a subtype.

const IMAGE_PNG: MediaType = MediaType::new(IMAGE, PNG);
assert_eq!(IMAGE_PNG, MediaType::parse("image/png").unwrap());

pub const fn from_parts( ty: Name<'a>, subty: Name<'a>, suffix: Option<Name<'a>>, params: &'a [(Name<'a>, Value<'a>)] ) -> Self

Constructs a MediaType with an optional suffix and parameters.

const IMAGE_SVG: MediaType = MediaType::from_parts(IMAGE, SVG, Some(XML), &[(CHARSET, UTF_8)]);
assert_eq!(
    IMAGE_SVG,
    MediaType::parse("image/svg+xml; charset=UTF-8").unwrap()
);

pub fn parse<'s: 'a>(s: &'s str) -> Result<Self, MediaTypeError>

Constructs a MediaType from str without copying the string.

Errors

Returns an error if the string fails to be parsed.

pub const fn essence(&self) -> MediaType<'_>

Returns a MediaType without parameters.

const IMAGE_SVG: MediaType = MediaType::from_parts(IMAGE, SVG, Some(XML), &[(CHARSET, UTF_8)]);
assert_eq!(
    IMAGE_SVG.essence(),
    MediaType::parse("image/svg+xml").unwrap()
);

Trait Implementations
