freezable
freezable
is a simple library for freezing data in Rust.
Objects which can be frozen implement the Freezable
trait, which provides a freeze
method. This returns a Frozen<T>
, which wraps the frozen type. The Frozen<T>
type implements all the comparison traits that T
implements, as well as Index
, Clone
, and Debug
, if the inner type implements them.
Why use this library?
The primary motivation for this library was frozen versions of HashMap
and HashSet
which support Hash
. This allows them to be used as keys in other HashMap
s and HashSet
s.
