Struct DefaultHasher

Help

1.7.0 · Source

pub struct DefaultHasher(/* private fields */);

Available on crate feature std only.

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.

Implementations§

Source §

impl DefaultHasher

1.13.0 · 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.
