Trait ForestObligation

pub trait ForestObligation: Clone + Debug {
    type CacheKey: Clone + Hash + Eq + Debug;

    // Required method
    fn as_cache_key(&self) -> Self::CacheKey;
}

Required Associated Types

type CacheKey: Clone + Hash + Eq + Debug

Required Methods

fn as_cache_key(&self) -> Self::CacheKey

Converts this ForestObligation suitable for use as a cache key. If two distinct ForestObligationss return the same cache key, then it must be sound to use the result of processing one obligation (e.g. success for error) for the other obligation

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.
