Trait KnownDist

pub trait KnownDist: Sized {
    type DistFn: DistFn<Self> + Sized;

    // Required method
    fn dist_fn() -> Self::DistFn;
}

Trait describing a type where a default distance function is known.

Required Associated Types

type DistFn: DistFn<Self> + Sized

The known distance function for Self.

Required Methods

fn dist_fn() -> Self::DistFn

Return an instance of DistFn.

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.
