pub trait FromStableHash: Sized {
type Hash;
// Required method
fn from(hash: Self::Hash) -> Self;
}Expand description
Trait for processing the result of the stable hashing operation.
§Example
use rustc_stable_hash::{StableHasher, FromStableHash};
struct Hash128(u128);
impl FromStableHash for Hash128 {
type Hash = [u64; 2];
fn from(hash: [u64; 2]) -> Hash128 {
let upper: u128 = hash[0] as u128;
let lower: u128 = hash[1] as u128;
Hash128((upper << 64) | lower)
}
}Required Associated Types§
Required Methods§
Sourcefn from(hash: Self::Hash) -> Self
fn from(hash: Self::Hash) -> Self
Convert the finalized state of a StableHasher and construct
an Self containing the processed hash.
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.
