This crate contains a basic parser for Bitcoin Payment Instructions.
It supports various encodings which you might encounter in QR codes, typed/pasted into a text box, or opened via a system URI handler.
Any missing Payment Instruction formats should be added as soon as there is a standard encoding for address formats, ideally using a Rust crate that (a) has very minimal dependencies, (b) has a fairly conservative MSRV policy, and (c) has regular contribution from more than one individual.
