Show HN: Static_str_ops: &'static str and non-const operations in Rust It is often asked by Rust programmer that how to create `&'static str` in Rust with non-const operations at runtime, e.g., returns the result of `format!()` as `&'static str`, rather than `String`. The crate static_str_ops addressed this issue, by allocating a hash set under the hood, and return the reference as the result. Along with this crate, a set of utilities are provided, including `static_format!`, `static_concat!`, and `staticize_once!` which can be used to initialize static strings with the `call_once` semantic. https://ift.tt/bXkUVFZ August 15, 2023 at 07:11PM
