Trait Relate

pub trait Relate<I>:
    TypeFoldable<I>
    + PartialEq
    + Copy
where
    I: Interner,
{
    // Required method
    fn relate<R>(
        relation: &mut R,
        a: Self,
        b: Self,
    ) -> Result<Self, TypeError<I>>
       where R: TypeRelation<I>;
}

Required Methods

fn relate<R>(relation: &mut R, a: Self, b: Self) -> Result<Self, TypeError<I>>

where R: TypeRelation<I>,

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.
