Macro radix_engine::define_composite_checker

macro_rules! define_composite_checker {
    (
        $ident: ident,
        [
            $($ty: ident $(< $( $generic_ident: ident: $generic_type: ty ),* $(,)? >)?),* $(,)?
        ] $(,)?
    ) => { ... };
}

Defines a composite application database checker that includes multiple other application database checkers.

This macro can be invoked as follows:

define_composite_checker! {
    CheckerIdent,
    [
        ResourceDatabaseChecker,
        RoleAssignmentDatabaseChecker
    ]
}

The above macro invocation will create a struct with the given ident which implements ApplicationChecker. Whenever one of the ApplicationChecker methods are called the data is passed to the ApplicationChecker implementation of the child checkers.
