compact_str VS STC

Not that I know of! As part of compact_str v0.6 we tried to make the API of CompactString 1:1 with String, inevitably we missed a few (1, 2, 3) things but they were fixed in this latest release.

... and more! Please see the CHANGELOG for more detail

(See the compact_str implementation as an example.)

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.

Doing this has been on the back of my mind for a while, just filed an issue to track this! #119

There's a draft pr for this.

Here're a few projects I considered interesting (including my own project) and relatively easy to participate: - pushgen Push-style design pattern for processing of ranges and data-streams. - compact_str A memory efficient immutable string type that can store up to 24* bytes on the stack - openssh-rs Scriptable SSH through OpenSSH in Rust - pegasus A multi-node parametrized command runner with a focus on simplicity - concurrent_arena Container that can have elements insert/removed concurrently and uses a 'u32' as key.

I wrote something similar to compact_str, but it is: - a Box when on the heap - (so clone is O(n)) - (but still immutable) - 2 usizes in size

This technique is often used to implement RAII in C. See example in Standard Template Containers. The library delivers STL-like functionality to C.

I'd say it's evil, but quite understandable very commonly used because there are no built-in alternatives in C. I basically never use void* in user-code, simply because there are no need for it when using a templating technique, like in my STC library. Even in the implementation of STC itself, void* is hardly used, if at all.

STC

This is more or less how C-ish templates are implemented in STC library.

As the author of a STL-like templated C container library, I had many of the exact same thoughts when implementing the unordered map. In fact, I also changed to many of the suggestions here, rather than consistently following the C++ umap API. E.g.

Sure it is. C misses a proper efficient generic standard/container library, like my https://github.com/stclib/STC, but that is irrelevant.

Smart Template Containers (STC)

Some data structure and algorithm library in C enable the (optional) separation between the interface of the container (which is expanded in your header) and its implementation (which is expanded in your source), like STC.
