qmc-decode

A lightweight command line tool to decode qmc file into mp3, flac or ogg. It offers more flexibilities than the original version written in C. Speedwise, the C version and this rust version is very similar -- they are both very fast. However,the rust version has much bigger build size. On macOS, it is about 791K after being stripped, while the C version is about 49K. I did not see much a difference stripping the C version -- it is tiny. Having said that, 791K is also tiny given that much more libraries are used.

Here is the command line help:
