Struct MediaType 

pub struct MediaType {
    pub type_: String,
    pub subtype: String,
    pub suffix: Option<String>,
}

A parsed media type: type/subtype with an optional structured-syntax suffix.

The suffix is None when the subtype has no +, and Some(_) otherwise — note it can be Some("") for a degenerate subtype like x++ (matching the reference), which is why round-tripping such a value back through format fails.

Fields

type_: String

The top-level type, e.g. application (lower-cased by parse).

subtype: String

The subtype, e.g. vnd.api (lower-cased by parse, suffix removed).

suffix: Option<String>

The structured-syntax suffix after the last +, e.g. json.

Implementations

impl MediaType

pub fn new( type_: impl Into<String>, subtype: impl Into<String>, suffix: Option<impl Into<String>>, ) -> Self

Construct a MediaType from its parts (without validation — use format to validate and render).

pub fn format(&self) -> Result<String, Error>

Validate and render this media type to a string. See format.

Errors

Returns an error if the type_, subtype, or suffix is not a valid RFC 6838 name.

Trait Implementations

impl Clone for MediaType

fn clone(&self) -> MediaType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MediaType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for MediaType

impl Hash for MediaType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MediaType

fn eq(&self, other: &MediaType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
