Struct IsoCountry 

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

ISO-3166-1 alpha-2 country code (e.g. US, GB, PK).

Validated on construction so a downstream validator never has to reject malformed strings. Stored upper-case for stable hashing and serde output; comparisons are case-insensitive at the boundary via IsoCountry::eq_ignore_ascii_case.

Example

use stygian_proxy::ports::coherence::IsoCountry;
let us = IsoCountry::new("us").unwrap();
assert_eq!(us.as_str(), "US");
assert!(IsoCountry::new("USA").is_none());
assert!(IsoCountry::new("u").is_none());

Implementations

impl IsoCountry

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

Parse and uppercase a two-letter country code.

Returns None when raw is not exactly two ASCII alpha characters; the validator treats unknown / malformed codes as CoherenceVerdict::Unknown rather than emitting false mismatches.

pub fn as_str(&self) -> &str

Returns the upper-case two-letter code.

pub fn eq_ignore_ascii_case(&self, other: &str) -> bool

Case-insensitive equality check for inbound config that may not have been normalised.

Example

use stygian_proxy::ports::coherence::IsoCountry;
let us = IsoCountry::new("US").unwrap();
assert!(us.eq_ignore_ascii_case("us"));
assert!(us.eq_ignore_ascii_case("Us"));
assert!(!us.eq_ignore_ascii_case("GB"));
