Struct HeaderValue

pub struct HeaderValue { /* private fields */ }

A header value.

Implementations

impl HeaderValue

pub fn from_bytes(bytes: Vec<u8>) -> Result<Self, Error>

Create a new HeaderValue from a Vec of ASCII bytes.

Error

This function will error if the bytes is not valid ASCII.

pub unsafe fn from_bytes_unchecked(bytes: Vec<u8>) -> Self

Converts a vector of bytes to a HeaderValue without checking that the string contains valid ASCII.

Safety

This function is unsafe because it does not check that the bytes passed to it are valid ASCII. If this constraint is violated, it may cause memory unsafety issues with future users of the HeaderValue, as the rest of the library assumes that Strings are valid ASCII.

pub fn as_str(&self) -> &str

Get the header value as a &str
