Derive Macro Event 

#[derive(Event)]
{
    // Attributes available to this derive:
    #[esrc]
}

Derive an Event implementation, with optional custom naming.

This defines the Event’s name as the name of the derived type, minus the “Event” suffix (if present), unless attributes are specified:

• esrc(event(name)) will override the name to the value specified. This is equivalent to implementing the trait manually.
• esrc(event(keep_suffix)) will not remove an “Event” suffix that is present on the type name.

Example

#[derive(Event)]
#[esrc(event(name = "BazEvent"))]
struct FooEvent;

#[derive(Event)]
struct BarEvent;

print!("{}", FooEvent::name()); // "BazEvent"
print!("{}", BarEvent::name()); // "Bar"
