Trait ForestObligation

source 
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§

source

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
