pub struct DataRequest {
    pub resource_path: ResourcePath,
}

Implementations

impl DataRequest

pub fn try_langid(&self) -> Result<&LanguageIdentifier, Error>

Returns the LanguageIdentifier for this DataRequest, or an error if it is not present.

Examples

use icu_provider::prelude::*;

const FOO_BAR: ResourceKey = icu_provider::resource_key!(x, "foo", "bar", 1);

let req_no_langid = DataRequest {
    resource_path: ResourcePath {
        key: FOO_BAR,
        options: ResourceOptions::default(),
    }
};

let req_with_langid = DataRequest {
    resource_path: ResourcePath {
        key: FOO_BAR,
        options: ResourceOptions {
            variant: None,
            langid: Some(icu_locid_macros::langid!("ar-EG")),
        },
    }
};

assert!(matches!(req_no_langid.try_langid(), Err(DataError::NeedsLanguageIdentifier(_))));
assert!(matches!(req_with_langid.try_langid(), Ok(_)));
