Trait HasEvents 

pub trait HasEvents {
    // Required method
    fn events() -> Vec<Event>;

    // Provided method
    fn event_schemas() -> BTreeMap<String, Schema> { ... }
}

A trait that should be implemented by each smart contract to allow the backend.

Required Methods

fn events() -> Vec<Event>

Returns a list of Events used by the contract.

Provided Methods

fn event_schemas() -> BTreeMap<String, Schema>

Returns a map of event schemas used by the contract.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
