Struct scale_info::prelude::collections::hash_map::DefaultHasher
1.13.0 · source · pub struct DefaultHasher(_);
Expand description
The default Hasher
used by RandomState
.
The internal algorithm is not specified, and so it and its hashes should not be relied upon over releases.
Implementations§
source§impl DefaultHasher
impl DefaultHasher
const: unstable · sourcepub fn new() -> DefaultHasher
pub fn new() -> DefaultHasher
Creates a new DefaultHasher
.
This hasher is not guaranteed to be the same as all other
DefaultHasher
instances, but is the same as all other DefaultHasher
instances created through new
or default
.
