Trait ConditionalEventHandler 

pub trait ConditionalEventHandler: Send + Sync {
    // Required method
    fn handle(
        &self,
        evt: &Event,
        n: RepeatCount,
        positive: bool,
        ctx: &EventContext<'_>,
    ) -> Option<Cmd>;
}

May behave differently depending on:

• edit mode (emacs vs vi)
• vi input mode (insert vs replace vs command modes)
• empty line
• cursor position
• repeat count
• original key pressed (when same command is bound to different key)
• hint
• …

Required Methods

fn handle( &self, evt: &Event, n: RepeatCount, positive: bool, ctx: &EventContext<'_>, ) -> Option<Cmd>

Takes the current input state and returns the command to be performed or None to perform the default one.

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