Get number of bytes written/read?

[alexreg]

Could the serialize_into and deserialize_from methods return the number of bytes written/read respectively? This would both handy and more efficient, since you already have to compute these values in these methods, and it thus saves an extra call to serialized_size.

Hmm, on second though, I'm not sure how easy this is to add to code.

If you use the structs defined here to do the deserialization you can grab the number of bytes read.

By using the function encoded_size, you can get the size of the struct as it would be on the wire.

It doesn't seem to be documented how to use those structs directly.

I've added documentation to rustc-serizlize DecoderReader and serde Deserializer. The encoded_size and serialized_size functions are already documented.

Thanks for this. That’s quite handy.

Not sure if it bothers you, but there’s a typo in the docs – “bytes_red”. Otherwise good.
