Struct ContentType 

pub struct ContentType {
    pub type_: String,
    pub subtype: String,
    pub params: Vec<(String, String)>,
}

A structured Content-Type / media type value.

Stores the type/subtype pair plus an optional list of name=value parameters. The Display implementation produces the canonical wire format, e.g. application/json or text/plain; charset=utf-8.

Fields

type_: String

The primary type (e.g. "application").

subtype: String

The subtype (e.g. "json").

params: Vec<(String, String)>

Optional parameters such as charset or boundary.

Implementations

impl ContentType

pub fn new(type_: String, subtype: String) -> Self

Construct a ContentType with no parameters.

pub fn with_params( type_: String, subtype: String, params: Vec<(String, String)>, ) -> Self

Construct a ContentType with parameters.

pub fn essence(&self) -> String

Return the type/subtype string without parameters.

use api_bones::content_type::ContentType;

let ct = ContentType::text_plain_utf8();
assert_eq!(ct.essence(), "text/plain");

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

Return the value of the named parameter, if present.

use api_bones::content_type::ContentType;

let ct = ContentType::text_plain_utf8();
assert_eq!(ct.param("charset"), Some("utf-8"));

pub fn application_json() -> Self

Returns application/json.

pub fn application_problem_json() -> Self

Returns application/problem+json (RFC 9457).

pub fn application_octet_stream() -> Self

Returns application/octet-stream.

pub fn multipart_form_data(boundary: impl Into<String>) -> Self

Returns multipart/form-data with the given boundary parameter.

pub fn text_plain() -> Self

Returns text/plain.

pub fn text_plain_utf8() -> Self

Returns text/plain; charset=utf-8.

pub fn text_html() -> Self

Returns text/html.

Trait Implementations

impl Clone for ContentType

fn clone(&self) -> ContentType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContentType

Available on crate feature serde only.

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for ContentType

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

Formats the value using the given formatter.

impl FromStr for ContentType

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse a Content-Type header value.

Accepts type/subtype with an optional ; name=value parameter list. Parameter names are lowercased; values are kept as-is.

type Err = ParseContentTypeError

The associated error which can be returned from parsing.

impl Hash for ContentType

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 ContentType

fn eq(&self, other: &ContentType) -> 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.

impl Serialize for ContentType

Available on crate feature serde only.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Eq for ContentType

impl StructuralPartialEq for ContentType
