A Rust-based assembler for the Hack language of 'From Nand to Tetris'.
Uses nom for parsing instructions-proper. While I had issues getting it to parse the entire input as a single parser, the instruction parsing worked great.
For this kind of task, Rust ends up feeling mostly perfect. A great balance between functional and systems concerns. And I quite appreciated being able to use the precise types I wanted, including a proper unsigned integer; looking at you, JVM.
