Rust rewrite
All functionality has been ported to the rust version.
To build it from the root of the repo, runmake rs, the optimised and stripped output binary will befcmp-rs.Debug targets
To build a debug binary, run
make debugin thefcmprsdirectory, or by invoking Cargo directly.
The output will betarget/debug/fcmprsfrom thefcmprsdirectory.Threading
By default the threaded strategy is compiled into the binary. Set
FEAT_RUSTvariable to disable this.PGO
Due to LLVM issues, PGO on the Rust version is broken at the moment.
You can try it with
cd fcmprs && make debugif you want.Performance
Crude profiling has suggested that the Rust version performs almost exactly the same as the C version when comparing large numbers of identical files. The C version slightly outperforms the Rust one is some other cases.
