Enum Locale 

pub enum Locale {
    Ca,
    De,
    Fr,
    Gb,
    It,
    Us,
}

A locale the pattern catalogue carries locale-specific detectors for.

Parse a user-supplied tag with str::parse or Locale::parse_optional; the variants are also usable directly (Locale::It).

Implementations

impl Locale

pub fn all() -> Vec<Self>

Every supported locale, in the order error messages list them.

pub fn as_str(&self) -> &'static str

The ISO 3166-1 alpha-2 code, as the pattern catalogue spells it.

pub fn parse_optional(tag: Option<&str>) -> Result<Option<Self>, String>

Parse an optional tag, where absent and blank both mean “no locale”.

This is the boundary helper for callers who receive a tag from a user or another language: None and "" are the same request (rank patterns without a locale preference), and every other value must resolve.

use dataprof_core::Locale;

assert_eq!(Locale::parse_optional(None), Ok(None));
assert_eq!(Locale::parse_optional(Some("  ")), Ok(None));
assert_eq!(Locale::parse_optional(Some("it-IT")), Ok(Some(Locale::It)));
assert!(Locale::parse_optional(Some("XX")).is_err());
