Trait Key

pub trait Key
where
    Self: Clone + Debug + Eq + Hash,
{
    // Required methods
    fn new() -> Self;
    fn as_filename(&self) -> String;
}

A datatype that can be used as the access key for cached items.

Note that this datatype when converted into a path, should not contain values that can be misinterpreted by the OS (e.g. path separators). I recommend UUIDv4 for most use cases.

Required Methods

fn new() -> Self

Generate a new, unique key.

fn as_filename(&self) -> String

Convert this key to a filename used for flushing to disk.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
