Trait InterfaceSpec 

pub trait InterfaceSpec: 'static {
    const IDS: &'static [Address];

    // Provided method
    fn contains(program_id: &Address) -> bool { ... }
}

Compile-time owner/program set for generic interface wrappers.

Implement this on a zero-sized marker type when a program context accepts one of several compatible programs. Interface<'info, I> validates an executable program account by key against this set, while InterfaceAccount<'info, T> validates account ownership through T::Interface.

Required Associated Constants

const IDS: &'static [Address]

Program IDs accepted by this interface.

Provided Methods

fn contains(program_id: &Address) -> bool

Whether program_id belongs to this interface.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
