sofd-error
One error type per OFD subsystem, each converting losslessly into a single taxonomy, so a caller can match on what went wrong without knowing which layer raised it.
This crate is transitive. It is on crates.io because sofd depends on it,
not because it is an interface — depend on sofd
instead, and this comes along.
Part of sOFD, a Rust engine for OFD documents.
