Macros

This crate provides a collection of macros that streamline and simplify development with the library. To use them, you need to add the openzeppelin_macros crate as a dependency in your Scarb.toml file:

openzeppelin_macros = "4.0.1"

Attribute macros

• with_components
• type_hash

Inline macros

generate_event_spy_helpers

generate_event_spy_helpers! generates Starknet Foundry EventSpy assertion methods from compact event declarations. Fields marked with #[key] become expected event keys, while all other fields become event data. Every declaration generates an assert_event_<event_name> method; adding #[only] also generates assert_only_event_<event_name>.

generate_event_spy_helpers! {
    impl TreasurySpyHelpers {
        #[only]
        event FundsReleased(
            #[key]
            recipient: ContractAddress,
            amount: u256
        );
    }
};

The generated implementation uses EventSpy, ExpectedEvent, and their assertion extensions, so bring the corresponding openzeppelin_testing types and traits into scope in the test module.
