Enum ContentTransferEncoding 

#[non_exhaustive]
pub enum ContentTransferEncoding {
    SevenBit,
    EightBit,
    Binary,
    QuotedPrintable,
    Base64,
    Other(String),
}

MIME content-transfer-encoding (RFC 2045 §6).

The five RFC-defined values are explicit variants; any other syntactically valid mime-token (e.g. an x- extension) round-trips through Other.

Casing

RFC 2045 §6.1 says encoding names are case-insensitive. Both the known-variant parser and the Other branch normalize to ASCII lowercase on construction, so equality and hashing through the derived impls are case-insensitive automatically: Other("Base64") is unreachable (parses to Base64 instead) and Other("X-MyEnc") stores "x-myenc".

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl ContentTransferEncoding

pub fn as_str(&self) -> &str

Trait Implementations

impl<'a> Arbitrary<'a> for ContentTransferEncoding

Available on crate feature arbitrary only.

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

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 ContentTransferEncoding

fn clone(&self) -> ContentTransferEncoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentTransferEncoding

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContentTransferEncoding

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 ContentTransferEncoding

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

Formats the value using the given formatter.

impl FromStr for ContentTransferEncoding

type Err = ContentTransferEncodingParseError

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 ContentTransferEncoding

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 ContentTransferEncoding

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

Generates a JSON Schema for this type.

impl PartialEq for ContentTransferEncoding

fn eq(&self, other: &ContentTransferEncoding) -> 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 ContentTransferEncoding

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 ContentTransferEncoding

type Error = ContentTransferEncodingParseError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for ContentTransferEncoding
