Trait SignalCallback 

pub trait SignalCallback {
    // Required method
    fn callback(
        &mut self,
        weechat: &Weechat,
        signal_name: &str,
        data: Option<SignalData<'_>>,
    ) -> ReturnCode;
}

Trait for the signal callback.

A blanket implementation for pure FnMut functions exists, if data needs to be passed to the callback implement this over your struct.

Required Methods

fn callback( &mut self, weechat: &Weechat, signal_name: &str, data: Option<SignalData<'_>>, ) -> ReturnCode

Callback that will be called when a signal is fired. input field.

Arguments

• weechat - A Weechat context.

• signal_name - The name of the signal that fired the callback.

• data - The data that was passed on by the signal.

Dyn Compatibility

This trait is dyn compatible.

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