Struct HeaderName 

pub struct HeaderName { /* private fields */ }

A header name that preserves its original ASCII casing while comparing case-insensitively.

Implementations

impl HeaderName

pub const fn new_static(original: &'static str, lower: &'static str) -> Self

Construct a header name from a 'static original/lowercase pair.

Both arguments must agree byte-for-byte modulo ASCII case. Use this for the entries in crate::keys.

pub fn new(name: impl Into<SmolStr>) -> Self

Construct a header name from an arbitrary string. The original casing is preserved; the lowercase form used for comparisons is computed eagerly.

pub fn original(&self) -> &str

The original-cased name as inserted by the caller.

pub fn as_str(&self) -> &str

The lowercase canonical form. Matches the on-the-wire HTTP/2 form.

Trait Implementations

impl AsHeaderName for HeaderName

fn as_lower(&self) -> Cow<'_, str>

Return the ASCII-lowercase form of this name. Borrows from the value when already lowercase, allocates otherwise.

impl AsHeaderName for &HeaderName

fn as_lower(&self) -> Cow<'_, str>

Return the ASCII-lowercase form of this name. Borrows from the value when already lowercase, allocates otherwise.

impl Clone for HeaderName

fn clone(&self) -> HeaderName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderName

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HeaderName

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

Deserialize this value from the given Serde deserializer.

impl Display for HeaderName

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

Formats the value using the given formatter.

impl Eq for HeaderName

impl From<&HeaderName> for HeaderName

fn from(value: &HeaderName) -> Self

Converts to this type from the input type.

impl From<&str> for HeaderName

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<SmolStr> for HeaderName

fn from(value: SmolStr) -> Self

Converts to this type from the input type.

impl From<String> for HeaderName

fn from(value: String) -> Self

Converts to this type from the input type.

impl Hash for HeaderName

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 HeaderName

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for HeaderName

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

Serialize this value into the given Serde serializer.
