Struct Headers 

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

HTTP header collection.

Header names are stored in normalized lowercase form for lookup, while the original raw casing is retained for serialization.

Implementations

impl Headers

pub fn iter(&self) -> impl Iterator<Item = (Vec<u8>, Vec<u8>)> + '_

Returns normalized (name, value) pairs.

Names are lowercase. Values preserve their stored bytes.

pub fn raw_items(&self) -> Vec<&(Vec<u8>, Vec<u8>, Vec<u8>)>

Returns raw (raw_name, normalized_name, value) header triples.

pub fn len(&self) -> usize

Returns the number of header fields.

pub fn is_empty(&self) -> bool

Returns true when the collection has no header fields.

pub fn new<I, N, V>(headers: I) -> Result<Self, ProtocolError>

where I: IntoIterator<Item = (N, V)>, N: AsRef<[u8]>, V: AsRef<[u8]>,

Builds and validates a header collection from byte-like name/value pairs.

This validates field syntax, normalizes names for lookup, preserves raw name casing for output, and enforces Content-Length / Transfer-Encoding consistency.

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

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 From<Vec<(Vec<u8>, Vec<u8>)>> for Headers

fn from(value: Vec<(Vec<u8>, Vec<u8>)>) -> Self

Builds headers from owned byte vectors.

This conversion panics if the headers are invalid. Prefer Headers::new when handling untrusted or fallible input.

impl Hash for Headers

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Headers

fn cmp(&self, other: &Headers) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Headers

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

impl PartialOrd for Headers

fn partial_cmp(&self, other: &Headers) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
