pub trait Hashable: Primitive + Eq + Hash { }Expand description
The subset of Primitive types that implement Eq and Hash.
Hashable types can be used as HashMap keys and in HashSets.
Examples: u8, u16, u32, u64, u128, i8, i16, i32, i64, i128, usize, bool, String
This trait lists the traits that are implemented for hashable types. Refer to the constituent traits to see proof definitions on methods.
Example
use opendp::traits::Hashable;
use std::collections::HashSet;
fn test_func<T: Hashable>(value: T) {
// can be debugged, as Hashable inherits all traits from Primitive
println!("{value:?}");
// can be used in hash sets and in the keys of hashmaps
let mut hashset = HashSet::new();
hashset.insert(value);
}
test_func("apple".to_string());
