Defines functions to interact with header data

Required Associated Constants

const HEADER_TYPE: HeaderType

The header type

Required Methods

fn header_count(&self) -> usize

Number of headers contained in block

Provided Methods

fn all(&self) -> Vec<(String, Vec<u8>)>

Get all headers in this block

fn get(&self, name: impl AsRef<str>) -> Option<Vec<u8>>

Check for a specific header value

fn set(&self, name: impl AsRef<str>, value: impl AsRef<[u8]>)

Set a specific header

fn set_all(&self, values: &[(&str, &[u8])])

Replace all headers in this block

fn add(&self, name: impl AsRef<str>, value: impl AsRef<[u8]>)

Add a header to this block (append to existing if present)

fn remove(&self, name: impl AsRef<str>)

Remove a header from this block

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
