Struct std::hash::DefaultHasher
1.7.0 · source · pub struct DefaultHasher(/* private fields */);
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
1.13.0 (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
.
