Required Methods

fn get<'life0, 'async_trait>( &'life0 mut self, key: String, ) -> Pin<Box<dyn Future<Output = Result<Result<Option<String>, Error>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Gets a configuration value of type string associated with the key.

The value is returned as an option<string>. If the key is not found, Ok(none) is returned. If an error occurs, an Err(error) is returned.

fn get_all<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Result<Vec<(String, String)>, Error>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Gets a list of configuration key-value pairs of type string.

If an error occurs, an Err(error) is returned.
