gecko-dev/third_party/rust/thin-vec/README.md

ThinVec is a Vec that stores its length and capacity inline, making it take up
less space. Currently this crate mostly exists to facilitate gecko ffi. The
crate isn't quite ready for use elsewhere, as it currently unconditionally
uses the libc allocator.
Bug 1457481 - Run mach vendor rust. r=froydnj,erahm Most importantly, this picks up "object" and "goblin" for ELF binary parsing. We only use the ELF code from goblin, so the mach-O parsing code gets eliminated by the linker. Overall, this increases the Android installer size by 20KB.
