Struct MediaType 

pub struct MediaType(/* private fields */);

An IANA media type such as image/png, or a top-level type such as image.

The wrapper does not validate syntax; it provides normalization helpers used when matching provider capabilities. Comparison is case-sensitive on the stored string; callers should normalize before comparing.

Implementations

impl MediaType

pub fn new(value: impl Into<String>) -> Self

Creates a media type from any string-like value.

pub fn as_str(&self) -> &str

Returns the media type as a string slice.

pub fn into_string(self) -> String

Consumes the media type and returns the inner String.

pub fn is_full(&self) -> bool

Returns true when the value is a full type/subtype media type.

A wildcard subtype (image/*) is not considered full.

pub fn top_level(&self) -> String

Returns the top-level type (image for image/png), lowercased.

pub fn subtype(&self) -> Option<&str>

Returns the subtype (png for image/png) without parameters, if any.

pub fn normalize(&self) -> MediaType

Normalizes the media type for capability matching.

Lowercases the value, drops parameters (; charset=utf-8) and turns a wildcard subtype (image/*) into its top-level type (image).

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

Returns true when this media type matches pattern.

pattern may be a full type, a wildcard (image/*) or a top-level type (image). Matching is case-insensitive and ignores parameters.
