Deserializing a String field inside a flattende struct fails if the field contains a valid integer

This does indeed look like a bug. I don't know when I'll have time to look into it, so patches are welcome if you can find a fix yourself.

I'll note that the presence of serde(flatten) concerns me. IIRC, it required some hacky things to make it work and it may not have been done correctly.

It seems like serde is calling deserialize_string for str, but deserialize_any for inner_str. Is this a bug in serde?

I don't know. I don't know much about serde internals. I do know that the serde(flatten) thing is a bit of a tortured feature though. It's one of those things that folks don't have to actually use, but it affords some very nice conveniences. But it just doesn't work in all cases.

I won't have time to look into this any time soon I'm afraid.

Yeah, it seems to be unsupported in serde: serde-rs/serde#1881

That's unfortunate :/
