Trait Equivalent 

pub trait Equivalent<T>: Sized {
    // Required methods
    fn into_equivalent(self) -> T;
    fn from_equivalent(object: T) -> Self;
}

Implemented if both types have the exact same layout. This implies having the same MaybeHasNiche::MnArray.

This is represented as two-way conversion for two reasons:

• to highlight that the conversion is actual equivalence
• to increase flexibility (mostly to go around the orphan rule)

Required Methods

fn into_equivalent(self) -> T

Inverse of Equivalent::from_equivalent.

fn from_equivalent(object: T) -> Self

Inverse of Equivalent::into_equivalent.

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.

Implementors

impl<U: 'static + Equivalent<T>, T: 'static, Extra: 'static> Equivalent<Point<T, Extra>> for Point<U, Extra>

This implementation is the main goal of Equivalent: we assume transmuting the pointer is safe.
