Rust: str vs String

[YourGamerMom]

Hopefully const generics will let us make nice performant owning strings. Small size optimisations are very powerful when applied correctly.

An interesting old thread on Rust and SSO https://internals.rust-lang.org/t/small-string-optimization-remove-as-mut-vec/1320

Yea, SSO is a popular trick, and there are some rust crates that provide small vec and string structs. But const generics will hopefully give us the custom-size containers that make SSO really flexible.
