Trait yewtil::Emissive

pub trait Emissive {
    type Message;
    fn emit(&self, msg: Self::Message);
}

Derivable trait used to simplify calling callbacks in pure components.

This trait is responsible for automating calling emit on a callback passed via props within types that implement PureComponent.

Note

When deriving, the derive macro will attempt to locate a field with a Callback<_>. type and use the inner type of the callback to specify the Message type of Emissive. The derived emit function will call self.<name of the callback struct>.emit(msg).

If it cannot find a callback struct, the Message type will be set to () and emit will do nothing.
