Trait SpecializationConstants 

pub unsafe trait SpecializationConstants {
    const ENTRIES: &'static [SpecializationMapEntry];

    // Required method
    fn as_ptr(&self) -> *const c_void;
}

A trait for types that can be used as specialization constants.

Safety

ENTRIES must be represent an content of this structs.

Required Associated Constants

const ENTRIES: &'static [SpecializationMapEntry]

Required Methods

fn as_ptr(&self) -> *const c_void

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.
