Announcing `compact_str` version 0.6! A small string optimization for Rust

• compact_str

  16 541 7.9 Rust

  A memory efficient string type that can store up to 24* bytes on the stack

Along with performance improvements, this release includes implementing multiple methods for CompactString, to bring its API nearly 1:1 with String. The only exception being methods that don't have a direct port for a small string optimization, e.g. into_bytes, or methods that aren't yet stable. A full change log can be found here.

  Comparison of Rust string types

  

SmolStr can online 22 characters and is immutable, but it is atomically ref counted so cloning is O(1). A good comparison of different string types can be found here

Very cool! I have a similar implementation in C where max stack/short string length is 23 characters, as C strings need a null-terminator. The last byte represents length as 23 - len, so when len is 23, it doubles as the null terminator (and it's high bit as the sso discriminator).
