Struct AcceptLanguage 

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

Accept-Language header value (RFC 7231 §5.3.5).

Captures the full header — en-US,en;q=0.9,fr;q=0.8 — so the validator can inspect the region of the highest-q entry without parsing on every call. The first / highest-priority entry is the one that drives the country agreement check.

Example

use stygian_proxy::ports::coherence::AcceptLanguage;
let al = AcceptLanguage::new("en-US,en;q=0.9").unwrap();
assert_eq!(al.as_str(), "en-US,en;q=0.9");
let primary = al.primary_region().unwrap();
assert_eq!(primary.as_str(), "en-US");

Implementations

impl AcceptLanguage

pub fn new(raw: &str) -> Option<Self>

Capture the raw header. Empty strings are rejected so the validator never sees a phantom “missing language” mismatch.

pub fn as_str(&self) -> &str

Returns the raw header value verbatim.

pub fn primary_region(&self) -> Option<Locale>

Highest-priority region parsed as a Locale (best-effort).

Returns None when the primary entry has no region subtag (e.g. en;q=1.0).
