Struct ContentType 

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

MIME content type.

Equality and hashing

PartialEq / Eq / Hash are derived. To make derived equality match RFC 2045 §5.1 semantics (type, subtype, and parameter names are case-insensitive), construction lowercases those tokens. Parameter values are preserved as-is because their case sensitivity depends on the parameter (boundary is case-sensitive per RFC 2046 §5.1.1; charset is case-insensitive per RFC 2046 §4.1.2 but the kernel leaves the caller’s bytes intact for round-trip fidelity).

Implementations

impl ContentType

pub fn as_str(&self) -> &str

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

Borrowed type/subtype view, with no parameters.

Cheap: it slices the stored string; no allocation. Validation guarantees a well-formed type/subtype prefix exists.

pub fn parameters(&self) -> impl Iterator<Item = (&str, ParameterValue<'_>)>

Iterate (name, value) parameter pairs in declaration order.

Quoted values are returned with surrounding quotes stripped and backslash escapes resolved.

pub fn parameter(&self, name: &str) -> Option<ParameterValue<'_>>

Look up a parameter by case-insensitive name.

pub fn boundary(&self) -> Option<ParameterValue<'_>>

Convenience accessor for the boundary parameter (multipart only).

pub fn charset(&self) -> Option<ParameterValue<'_>>

Convenience accessor for the charset parameter.

Trait Implementations

impl<'a> Arbitrary<'a> for ContentType

Available on crate feature arbitrary only.

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

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: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

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 From<ContentType> for String

fn from(value: ContentType) -> Self

Converts to this type from the input type.

impl FromStr for ContentType

type Err = ContentTypeParseError

The associated error which can be returned from parsing.

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

Parses a string s to return a value of this type.

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 JsonSchema for ContentType

Available on crate feature schemars only.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(_generator: &mut SchemaGenerator) -> Schema

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for ContentType

type Error = ContentTypeParseError
