Trait Application 

pub trait Application: Sized {
    type Err: Send + 'static;
    type Config: Config;
    type Options: Options;

    // Required methods
    fn new(_: Self::Options, _: Self::Config) -> Result<Self, Self::Err>;
    fn run_once(&mut self, context: &Context) -> Result<Stopping, Self::Err>;

    // Provided methods
    fn signals() -> &'static [Signal] { ... }
    fn received_signal(&mut self, _: Signal) { ... }
    fn shutdown(self) -> Result<(), Self::Err> { ... }
}

The application; domain-specific program logic

Required Associated Types

type Err: Send + 'static

Main error export of the Application

type Config: Config

Config to be loaded from a file

type Options: Options

Options from the command line

Required Methods

fn new(_: Self::Options, _: Self::Config) -> Result<Self, Self::Err>

Create a new instance given the options and config

fn run_once(&mut self, context: &Context) -> Result<Stopping, Self::Err>

Called repeatedly in the main loop of the application.

Provided Methods

fn signals() -> &'static [Signal]

Which signal the application is interested in receiving.

By default, only INT and TERM are blocked and handled.

fn received_signal(&mut self, _: Signal)

Handle a received signal

fn shutdown(self) -> Result<(), Self::Err>

Called when the application is shutting down

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
