string_compressor

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?
