DefaultHasher

Struct DefaultHasher 

1.76.0 ยท 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.

Implementationsยง

Sourceยง

impl DefaultHasher

1.13.0 (const: unstable) ยท Source

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.
