Required Methods

fn as_clause(self) -> Option<<I as Interner>::Clause>

fn is_coinductive(self, interner: I) -> bool

fn allow_normalization(self) -> bool

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.
