const TYPE: &'static str

A unique identifier for this trigger.

Required Associated Types

type CliArgs: Args

The specific CLI arguments for this trigger.

type InstanceState: Send + 'static

The instance state for this trigger.

Required Methods

fn new(cli_args: Self::CliArgs, app: &App) -> Result<Self>

Constructs a new trigger.

fn run( self, trigger_app: TriggerApp<Self, F>, ) -> impl Future<Output = Result<()>> + Send

Run this trigger.

Provided Methods

fn add_to_linker( &mut self, linker: &mut Linker<InstanceState<<F as RuntimeFactors>::InstanceState, <Self as Trigger<F>>::InstanceState>>, ) -> Result<()>

Update the Linker for this trigger.

fn supported_host_requirements() -> Vec<&'static str>

This trait is not dyn compatible.

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