smartstring | Compact inlined strings for Rust

smartstring is a Rust library. smartstring has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

This crate provides a wrapper for Rust's standard String which uses the space a String occupies on the stack to store inline string data, automatically promoting it to a String when it grows beyond the inline capacity. This has the advantage of avoiding heap allocations for short strings as well as improving performance thanks to keeping the strings on the stack. This is all accomplished without the need for an external discriminant, so a SmartString is exactly the same size as a String on the stack, regardless of whether it's inlined or not. Converting a heap allocated SmartString into a String and vice versa is also a zero cost operation, as one will reuse the allocated memory of the other.
