>                 URL: https://issues.apache.org/jira/browse/THRIFT-5458
>             Project: Thrift
>          Issue Type: Improvement
>          Components: Rust - Library
>            Reporter: Jorge Leitão
>            Priority: Major

> Currently we ignore how many bytes were read in total after parsing objects. However, in some applications, this information is very useful as it allows to know how many bytes were moved in a file descriptor.
> The current hack to this is to require the trait `Seek` and perform 2 seeks, one before reading and one after reading. However, not all readers support cheap seek operations.
> I would like to propose that we change our signatures of `read_` and `write_` to return Result<usize>, with the number of bytes read and write respectively.
> The calculation of the number of bytes is just a sum over all bytes read, which amounts to summing the results of the internal `read_` calls.
