Trait icu_provider::prelude::DataProvider

pub trait DataProvider<'d> {
    fn load<'a>(&'a self, req: &DataRequest) -> Result<DataResponse<'d>, Error>;
}

An abstract data provider that takes a request object and returns a response with a payload. Lifetimes:

• 'a = lifetime of the DataProvider object
• 'd = lifetime of the borrowed payload Note: 'd and 'a can be the same, but they do not need to be. For example, 'd = 'static if:

1. The provider always returns data that lives in static memory
2. The provider always returns owned data, not borrowed data

Required methods

fn load<'a>(&'a self, req: &DataRequest) -> Result<DataResponse<'d>, Error>

Query the provider for data. Returns Ok if the request successfully loaded data. If data failed to load, returns an Error with more information.
