pub fn version() -> &'static str cargo add ucallThe crate links the UCall library, which its build script compiles through CMake, so building needs CMake and a C++20 compiler. CMake builds StringZilla, ForkUnion and SmashTable from the trees of those crates, which the crate depends on, rather than fetching them again. The library picks its I/O backend and CPU kernels when a server or client starts, so one build adapts to the kernel and CPU it runs on.
