1//! The crate error taxonomy.
2//!
3//! Every fallible operation in dig-options returns [`Result`], whose error is [`Error`].
4//! The variants separate the three failure sources a pure builder can hit: a lower-level
5//! driver failure while constructing a spend, a signer failure while computing the required
6//! signatures, and caller-supplied input that cannot produce a valid spend.
