Struct Headers 

pub struct Headers { /* private fields */ }

A map of HTTP headers (single value per name). Headers can be layered; later values override earlier ones.

Note: This type keeps a single value per header name, which is the most intuitive behavior for genai. It enables straightforward auth and other overrides.

Implementations

impl Headers

pub fn merge(&mut self, overlay: impl Into<Headers>)

Merge headers from overlay into self, consuming overlay. Later values override existing ones. Use [merge_with] for a borrowed overlay.

pub fn merge_with(&mut self, overlay: &Headers)

Merge headers from overlay into self without consuming it. Later values override existing ones.

pub fn applied_to(self, target: impl Into<Headers>) -> Headers

Apply self on top of target, consuming both, and return the result. Values in self override those in target.

impl Headers

pub fn iter(&self) -> Iter<'_, String, String>

Returns an iterator over (name, value) pairs.

pub fn iter_mut(&mut self) -> IterMut<'_, String, String>

Returns a mutable iterator over (name, value) pairs.

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<'de> Deserialize<'de> for Headers
