Struct mediatype::MediaTypeBuf

pub struct MediaTypeBuf { /* private fields */ }

An owned and immutable MediaType.

use mediatype::{names::*, values::*, MediaType, MediaTypeBuf, ReadParams};

let text_plain: MediaTypeBuf = "text/plain; charset=UTF-8".parse().unwrap();
assert_eq!(text_plain.get_param(CHARSET).unwrap(), UTF_8);

let mut text_markdown: MediaType = text_plain.to_ref();
text_markdown.subty = MARKDOWN;
assert_eq!(text_markdown.to_string(), "text/markdown; charset=UTF-8");

Implementations

impl MediaTypeBuf

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

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

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

Constructs a MediaTypeBuf with an optional suffix and parameters.

pub fn from_string(s: String) -> Result<Self, MediaTypeError>

Constructs a MediaTypeBuf from String.

Unlike FromStr::from_str, this function takes the ownership of String instead of making a new copy.

pub fn ty(&self) -> Name<'_>

Returns the top-level type.

pub fn subty(&self) -> Name<'_>

Returns the subtype.

pub fn suffix(&self) -> Option<Name<'_>>

Returns the suffix.

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

Returns a MediaType without parameters.

let media_type: MediaTypeBuf = "image/svg+xml; charset=UTF-8".parse().unwrap();
assert_eq!(media_type.essence().to_string(), "image/svg+xml");

pub fn as_str(&self) -> &str

Returns the underlying string.

pub fn canonicalize(&self) -> Self

Returns the canonicalized MediaTypeBuf.

All strings except parameter values will be converted to lowercase.

let media_type: MediaTypeBuf = "IMAGE/SVG+XML;  CHARSET=UTF-8;  ".parse().unwrap();
assert_eq!(
    media_type.canonicalize().to_string(),
    "image/svg+xml; charset=UTF-8"
);

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

Constructs a MediaType from self.
