Implementations

impl MessageHeaders

pub const fn new() -> Self

Creates an empty message-header collection.

pub fn with_field(self, field: HeaderField) -> Self

Adds a header field and returns the updated collection.

pub fn push(&mut self, field: HeaderField)

Appends a field.

pub fn fields(&self) -> &[HeaderField]

Returns fields.

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

Finds the first header value by case-insensitive name.

Trait Implementations

impl Clone for MessageHeaders

fn clone(&self) -> MessageHeaders

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageHeaders

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

Formats the value using the given formatter.

impl Default for MessageHeaders

fn default() -> MessageHeaders

Returns the “default value” for a type.

impl Display for MessageHeaders

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

Formats the value using the given formatter.

impl PartialEq for MessageHeaders

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
