Trait ReflectHash 

pub trait ReflectHash {
    const HASH: [u8; 32];
}

Core trait for computing structural compile-time hashes.

Types implementing this trait can be hashed at compile time to produce a unique 32-byte identifier based solely on their structure, not their names.

Deriving

Most types should use #[derive(ReflectHash)] which automatically generates the correct implementation based on the type’s structure.

Required Associated Constants

const HASH: [u8; 32]

The 256-bit structural hash of this type, computed at compile time.

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.
