cms builders: infallible methods with `Result<_>` return type
I'm only working with SignedData & SignerInfo, I haven't checked the other builders, but these methods are all infallible, why do they return Result<_>?
-
SignedDataBuilder::add_digest_algorithm -
SignedDataBuilder::add_certificate -
SignedDataBuilder::add_crl -
SignerInfoBuilder::new -
SignerInfoBuilder::add_signed_attribute -
SignerInfoBuilder::add_unsigned_attribute
Would you be open to returning the unwrapped types? The current approach strikes me as unnecessary, and creates a lot of boilerplate in my specific use case where I'm using anyhow to catch errors, which relies on the std/core Error trait for ? coercion (not implemented on v0.2, though I can see it in the v0.3 prereleases).
Despite opening a few issues on this repo in a relatively short timeframe, I'd like to emphasise that my experience across several of the RustCrypto crates has been overwhelmingly positive! Everything I've wanted to do has an API/trait, has felt ergonomic, and has worked once it's compiled ❤️
