Automatic interface satisfying check

[adex-codez]

For every type which implements an interface an automatic check for if the type implements the interface like go's interface

How do you propose creating an automatic check? I could be missing your question, sorry. But this function (satisfiedBy) exists on the Interface you create to check:

const Repository = Interface(.{...});

// In functions that accept interface implementations:
fn createUser(repo: anytype, name: []const u8, email: []const u8) !User {
    comptime Repository.satisfiedBy(@TypeOf(repo));
    // ... rest of implementation
}

// Or verify directly:
comptime Repository.satisfiedBy(InMemoryRepository); // where `InMemoryRepository` is the struct implementing `Repository`

@adex-codez - the latest updates should be much more aligned to automatically check (still a small step to construct/convert into the interface type from a concrete impl). Check it out and lmk what you think. PR at #9.
