Struct std::collections::hash_map::DefaultHasher 1.13.0
[−]
[src]
pub struct DefaultHasher(_);
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.
Methods
impl DefaultHasher
[src]
pub fn new() -> DefaultHasher
[src]
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
.
