Struct std::collections::hash_map::DefaultHasher

[+] Show declaration

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.

Methods

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.
