Struct std::collections::hash_map::DefaultHasher
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.
Implementations
impl 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.
