Jorge Leitão updated THRIFT-5458:
---------------------------------
Summary: Return how many bytes were written (was: Return how many bytes
were read and written)
> Return how many bytes were written
> ----------------------------------
>
> Key: THRIFT-5458
> 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.
