Trait GroupKey 

pub trait GroupKey: IndexDomain {
    // Required method
    fn resolve_key<'a>(
        label: &'static str,
        graphrecord: &'a GraphRecord,
        key: &Self::Owned,
    ) -> QueryResult<Self::Index<'a>>;
}

Required Methods

fn resolve_key<'a>( label: &'static str, graphrecord: &'a GraphRecord, key: &Self::Owned, ) -> QueryResult<Self::Index<'a>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
