swap-cpp-rust

A small comparative bench of std::swap to assert its actual behavior

Rust bench

To launch the Rust Criterion benchmark:

cargo bench

It is also possible to compare implementation through binaries:

cargo build -r && hyperfine --shell=none \
                      "./target/release/swap 10" \
                      "./target/release/swap 1000000" \
                      "./target/release/naive_swap 10" \
                      "./target/release/naive_swap 1000000"

C++ bench

To observe scaling of C++ std::swap on std::vector:

cmake -S . -B build && cmake --build build && hyperfine "./build/main 10" "./build/main 1000000"
