Struct MediaType 

pub struct MediaType {
    pub typ: String,
    pub subtype: String,
    pub params: Vec<(String, String)>,
}

A parsed media type (MIME type) with optional parameters.

Represents types like text/html, application/json, or text/html; charset=utf-8.

Fields

typ: String

The primary type (e.g., “text”, “application”, “image”).

subtype: String

The subtype (e.g., “html”, “json”, “png”).

params: Vec<(String, String)>

Optional parameters (e.g., charset, boundary).

Implementations

impl MediaType

pub fn parse(s: &str) -> Option<Self>

Parse a media type string.

Example

let mt = MediaType::parse("text/html; charset=utf-8").unwrap();
assert_eq!(mt.typ, "text");
assert_eq!(mt.subtype, "html");

pub fn new(typ: impl Into<String>, subtype: impl Into<String>) -> Self

Create a new media type without parameters.

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

Check if this media type matches another, supporting wildcards.

A wildcard * matches any value.

Example

let html = MediaType::new("text", "html");
let any_text = MediaType::new("text", "*");
let any = MediaType::new("*", "*");

assert!(html.matches(&any_text));
assert!(html.matches(&any));
assert!(!any_text.matches(&html)); // wildcard doesn't match specific

pub fn essence(&self) -> String

Returns the media type as a string without parameters.

pub fn param(&self, name: &str) -> Option<&str>

Get a parameter value by 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 Display for MediaType

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

Formats the value using the given formatter.

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.
