Safe Rust wrapper formecab a japanese language part-of-speech and morphological analyzer library.

The wrapper is almost identical to the C++ interface of mecab with the addition of various iterator for comfortable data access. It is build with the latest version of mecab v0.996.

Both Windows Rust versions (MSVC ABI and gcc toolchain) can just use theprebuilt 32bit library.Using mecab-rs with the Windows commandline is not recommended and can causeundefined behavior if you are not using the correct codepage and a font that supports japanese character.

CMake & 64bit library:

• CMake config for mecab
• 64bit MSVC library and binaries
• 64bit GCC library and binaries

Thanks to@DoumanAsh for providing these files

Include this in your Cargo.toml to add mecab to your project:
