Provided Methods§

Source

fn next_trait_solver(&self) -> bool

Whether the new trait solver is enabled. This only exists because rustc shares code between the new and old trait solvers; for all other users, this should always be true. If this is unknowingly false and you try to use the new trait solver, things will break badly.

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.
