Trait dotrix_egui::epaint::ahash::CallHasher [−]
pub trait CallHasher {
fn get_hash<H, B>(value: &H, build_hasher: &B) -> u64
where
B: BuildHasher,
H: Hash + ?Sized;
}Expand description
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.
Example
use std::hash::BuildHasher;
use ahash::RandomState;
use ahash::CallHasher;
let hash_builder = RandomState::new();
//...
let value = 17;
let hash = u32::get_hash(&value, &hash_builder);
