A Rust port of https://github.com/oisyn/parkerwords/ C++ implementation.

Please note that it is not fair to compare the reading time, since the text file is basically built into the binary here. Everything else should be comparable.

Note

Cross-link to Golang implementation, which is suprisingly fast https://github.com/yarcat/parkerwords-go
