Struct HeaderValue 

pub struct HeaderValue { /* private fields */ }

HeaderValue type

Note: Unlike HeaderValue in http, this only supports UTF-8 header values

Implementations

impl HeaderValue

pub fn as_str(&self) -> &str

Returns the string representation of this header value

Panics

If the value is not valid UTF-8. A HeaderValue stored in a Headers may be of any encoding, so prefer try_as_str or as_bytes unless the value is one you constructed yourself, which is necessarily valid UTF-8 because the only public constructors (FromStr and TryFrom<String>) take a str.

No accessor on Headers hands out a HeaderValue, so this is not reachable through one. Note From<HeaderValue> for String panics for the same reason.

pub fn as_bytes(&self) -> &[u8]

Returns the bytes of this header value exactly as they were received

Unlike as_str, this is always available.

pub fn try_as_str(&self) -> Option<&str>

Returns the string representation of this header value, or None if it is not valid UTF-8

Trait Implementations

impl AsRef<str> for HeaderValue

fn as_ref(&self) -> &str

Panics

If the value is not valid UTF-8. See HeaderValue::as_str.

impl Clone for HeaderValue

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderValue

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

Formats the value using the given formatter.

impl From<HeaderValue> for String

fn from(value: HeaderValue) -> Self

Converts to this type from the input type.

impl FromStr for HeaderValue

type Err = HttpError

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 TryFrom<String> for HeaderValue

type Error = HttpError

The type returned in the event of a conversion error.

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

Performs the conversion.
