Trait icu_provider::prelude::DataProvider [−][src]
pub trait DataProvider<'data, M> where
M: DataMarker<'data>, {
fn load_payload(
&self,
req: &DataRequest
) -> Result<DataResponse<'data, M>, Error>;
}Expand description
A generic data provider that loads a payload of a specific type.
See examples on some of the concrete implementations:
Required methods
fn load_payload(
&self,
req: &DataRequest
) -> Result<DataResponse<'data, M>, Error>
fn load_payload(
&self,
req: &DataRequest
) -> Result<DataResponse<'data, M>, Error>
Query the provider for data, returning the result.
Returns Ok if the request successfully loaded data. If data failed to load, returns an
Error with more information.
