Trait Equivalence

pub unsafe trait Equivalence {
    type Out: Datatype;

    // Required method
    fn equivalent_datatype() -> Self::Out;
}

A direct equivalence exists between the implementing type and an MPI datatype

Standard section(s)

3.2.2

Required Associated Types

type Out: Datatype

The type of the equivalent MPI datatype (e.g. SystemDatatype or UserDatatype)

Required Methods

fn equivalent_datatype() -> Self::Out

The MPI datatype that is equivalent to this Rust type

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.
