Trait CallHasher

pub(crate) trait CallHasher {
    // Required method
    fn get_hash<H: Hash + ?Sized>(value: &H, random_state: &RandomState) -> u64;
}

Provides a way to get an optimized hasher for a given data type. Rather than using a Hasher generically which can hash any value, this provides a way to get a specialized hash for a specific type. So this may be faster for primitive types.

Required Methods

fn get_hash<H: Hash + ?Sized>(value: &H, random_state: &RandomState) -> u64

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.
