<p>The <code>rayon</code> and <code>mmap</code> Cargo features enable additional methods on this
|

type related to multithreading and memory-mapped IO.</p>
|
||
<p>When the <code>traits-preview</code> Cargo feature is enabled, this type implements
|
||
several commonly used traits from the
|
||
<a href="https://crates.io/crates/digest"><code>digest</code></a> crate. However, those
|
||
traits aren’t stable, and they’re expected to change in incompatible ways
|
||
before that crate reaches 1.0. For that reason, this crate makes no SemVer
|
||
guarantees for this feature, and callers who use it should expect breaking
|
||
changes between patch versions.</p>
