Struct Headers 

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

Case-insensitive header collection.

Stored as a list rather than a map because HTTP allows repeated headers and the order occasionally matters.

Implementations

impl Headers

pub fn new() -> Self

pub fn insert(&mut self, name: impl Into<String>, value: impl Into<String>)

pub fn append(&mut self, name: impl Into<String>, value: impl Into<String>)

pub fn get(&self, name: &str) -> Option<&str>

pub fn get_u64(&self, name: &str) -> Option<u64>

Parse a header value as a number, ignoring anything unparseable.

A malformed rate-limit header is not worth failing a request over.

pub fn iter(&self) -> impl Iterator<Item = (&str, &str)>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

Trait Implementations

impl Clone for Headers

fn clone(&self) -> Headers

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Headers

Redacting Debug.

A tracing::debug!(?headers, ...) anywhere in the stack would otherwise print bearer tokens into the log file.

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

Formats the value using the given formatter.

impl Default for Headers

fn default() -> Headers

Returns the “default value” for a type.

impl Eq for Headers

impl<K: Into<String>, V: Into<String>> FromIterator<(K, V)> for Headers

fn from_iter<I: IntoIterator<Item = (K, V)>>(entries: I) -> Self

Creates a value from an iterator.

impl PartialEq for Headers

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

Equality operator ==.

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

Inequality operator !=.
