Yes, see "rust_abi: 'rust'". I think you can't even do "extern crate" with a staticlib - the only staticlib is the per-target one that is put together via scripts/rust/rust_root_crate.sh. In theory https://github.com/mesonbuild/meson/pull/14818 should allow removing the staticlib as well, using rustc instead of gcc to create the final executable even if it has system/main.c listed as one of its sources. Executables should than be smaller or they can use dynamic libstd. I haven't tested that yet though... Paolo
