This repo tries to assess Rust string types.

We currently compare:

Suggestions:

• Generally, String
• If you deal mostly with string literals but want some flexibility (like clap), generally you'll want Cow<'static, str>
• If a profiler says your strings are a problem:
  • Try different crates and settings for that crate out with a profiler
  • O(1) clones are important when doing a lot of clones. For one-off allocations, they are slower.
  • For short-lived programs, look into string interning

Note: smol_str was removed in favor of ecow

Terms:

• Heap: will store strings in heap-allocated memory
• Inline: will store small-enough strings on the stack
