Struct std::collections::hash::map::DefaultHasher

1.13.0 · source ·
pub struct DefaultHasher(SipHasher13);
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.

Tuple Fields§

§0: SipHasher13

Implementations§

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.
