Binary Size

September 10, 2024 · View on GitHub

The binary size comparisons were run on an Intel(R) Core(TM) i7-6560U CPU @ 2.20GHz processor, on Linux 5.12.5/Fedora 34, and run against commit 8406144. The Rust compiler version was rustc 1.55.0-nightly (b41936b92 2021-07-20).

Each binary is generated using all optimization levels, and includes the result before and after stripping, with the core functionality black-boxed, to ensure optimization does not optimize-out the result.

All these binaries sizes are relative to the size of an empty Rust binary: that is, the size of the empty executable is subtracted from the total binary's size. For some cases, this leads to results of 0 bytes, which isn't real, but in practice leads to no additional size in the resulting executable.
