What does this library do?
It exports the StringCompressor
struct that can be used to create minimally compact, non-colliding,
URL-safe, base-64 aliases for a set of strings. In simple terms, it's a very fast hasher that optimizes for small hash sizes.
When should I use this?
- When you need to hash strings and need your hashed values to be as small as possible.
- When you need hashed values to be safe for use in URLs and file names.
- When you need to un-hash previously hashed strings.
When should I use something else?
- When you need to uniquely hash more than 2^64 strings using a single instance. In the future,
StringCompressor
will support higher concurrently unique hashes.
- When you need your hasher not to affect memory usage. In the future,
StringCompressor
will support a future flag that allows zero scaling in memory, at the expense of disallowing un-hashing.
- When hashed values need to be transmitted and un-hashed by another program.
What characters can a hashed value contain?
- Lowercase and uppercase alphabetical ASCII characters:
a
through z
and A
through Z
- Numerical ASCII characters:
0
through 9
- Dashes and underscores:
-
and _
- Hashed values are un-padded to minimize size.
How can I use this in my own Rust project?
