Goals

• Correct for correct input.
• Only events - not files.
• Fast and easy for compiler to inline/optimize. (This includes ignoring the top bit rather than checking it, for example).
• Ideally as fast as working with raw bytes, but more ergonomic.
• Memory safe, even on bad input (this is the time we are willing to sacrifice performance).
• #[no_std]

Stretch

• Deal with malformed messages
• Deal with common sysex messages, but not in a way that harms performance of the standard case.

Non-goals

• Parsing smf files
• Easy to understand code
• #![unsafe(never)]
