Internally tagged enumerations cannot deserialize byte buffers

[RReverser]

Does this work for deserialization from other formats? For example, you could try to serialize some data to https://docs.rs/bincode/latest/bincode/ and then parse it back. If it doesn't work with other formats, then likely there isn't much we can do either.

Generally, serde has a lot of problems with internally tagged enums, because it first deserializes them into an internal "fat" container with all kinds of data, and then tries to convert from that into the destination format.

The problem with that approach is that, of course, only types that serde hardcoded in its internal representation are supported, while more esoteric ones - likely, including byte buffers - are not.

See serde-rs/serde#1183 for more details.

I'm going to close this as I'm fairly sure this is the linked upstream issue and not something we can fix on our side.
