Struct HeaderValue 

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

A header value. Use HeaderValue::from_static for 'static str literals to avoid allocation.

Implementations

impl HeaderValue

pub const fn from_static(s: &'static str) -> Self

Construct from a 'static string literal at compile time.

pub fn from_string(s: String) -> Self

Construct from an owned String. Allocates only if the input is non-empty.

pub fn as_str(&self) -> &str

Borrow the value as a &str.

pub fn len(&self) -> usize

Length of the value in bytes.

pub fn is_empty(&self) -> bool

Whether the value is empty.
