Custom tuple parser, types of fields, raw tuple data.

[chertov]

Please consider making the method Tuple::as_buffer(&self) -> Result<Vec<u8>, Error> public.
I would like to parse unknown tuples with RMP crate.

tarantool-module/src/tuple.rs

Line 144 in e77a6cb

pub(crate) fn as_buffer(&self) -> Result<Vec<u8>, Error> {

example:

let buf = tuple.as_buffer()?;
let value = rmpv::decode::read_value(&mut &buf[..])?;
debug!("{:?}", value);

Or maybe is it possible to return the type of field by the filed index?

Sorry for the late reply. You can use Tuple::as_struct method for that like so:

let value = tuple.as_struct::<rmpv::Value>()?;
dbg!(value);

Don't forget to enable with-serde feature in rmpv crate:

[dependencies]
rmpv = { version = "^1.0", features = ["with-serde"] }
