Crate bip21

Rust-idiomatic, compliant, flexible and performant BIP21 crate.

Important: while lot of work went into polishing the crate it’s still considered early-development!

• Rust-idiomatic: uses strong types, standard traits and other things
• Compliant: implements all requirements of BIP21, including protections to not forget about req-. (But see features.)
• Flexible: enables parsing/serializing additional arguments not defined by BIP21
• Performant: uses zero-copy deserialization and lazy evaluation wherever possible.

Serialization and deserialization is inspired by serde with these important differences:

• Deserialization signals if the field is known so that req- fields can be rejected.
• Much simpler API - we don’t need all the features.
• Use of [Param<'a>] to enable lazy evaluation.

The crate is no_std but does require alloc.

Features

• std enables integration with std - mainly std::error::Error.
• non-compliant-bytes - enables use of non-compliant API that can parse non-UTF-8 URI values.
