[−][src]Trait lambda_runtime_core::ConfigProvider

pub trait ConfigProvider {
    fn get_function_settings(&self) -> Result<FunctionSettings, RuntimeError>;

    fn get_runtime_api_endpoint(&self) -> Result<String, RuntimeError>;
}

Trait used by the RustRuntime module to retrieve configuration information about the environement. This is implemented by the EnvConfigProvider using the environment variables. We also have a mock implementation for the unit tests

Required methods

fn get_function_settings(&self) -> Result<FunctionSettings, RuntimeError>

Loads the function settings such as name, arn, memory amount, version, etc.

Return

A Result of FunctionSettings or a RuntimeError. The runtime fails the init process if this function returns an error.

fn get_runtime_api_endpoint(&self) -> Result<String, RuntimeError>

Returns the endpoint (hostname:port) for the Runtime API endpoint
