Trait ReloadSource 

pub trait ReloadSource {
    // Required method
    fn recv(&mut self) -> Option<()>;
}

A source of reload triggers. recv blocks until the next trigger fires, or returns None when the source is exhausted / shut down (the loop then ends). Implementors carry no config: a trigger only ever means “re-read the manifest now”.

Required Methods

fn recv(&mut self) -> Option<()>

Block until the next reload trigger; None ends the reload loop.

Dyn Compatibility

This trait is dyn compatible.

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