serde_derive does not currently support using integer values as map
keys. CTAP uses integer values for various CBOR map keys. In order to
properly serialize and deserialize types for the CTAP protocol, a forked
version of serde from a pull request that adds support for renaming
field keys as integer types is used.
Tracked in <https://github.com/serde-rs/serde/pull/2209>
Adds serde_with as a dependency in order to serialize Descriptor::id as
bytes instead of as a sequence.
Enables cfg_eval feature to enable conditional usage of serde_with
behind the "serde" feature flag for the fido-common crate.
Relies on ciborium as a dependency because coset requires one of
ciborium's error types. It should be possible to remove this type's
dependence on ciborium.
bounded_vec crate was used to enforce constraints on size of various
fields as defined by webauthn or ctap specs. However, it does not
properly support zero-sized lower bounds.
