-------------------------------------
was (Author: JIRAUSER301413):
[~mgrigorov], can you explain to me how to get the `Value`
using `SpecificSingleObjectWriter` or `SpecificSingleObjectWriter`
>From data like :
```
#[derive(Serialize)]
struct Toto
{ data: u8, }
```
without implementing `AvroSchema` trait
Thanks
> Open the visibility of serde implementation

> Hi everyone :)
> We at Clever Cloud are working on a storage format using the Avro
> specification for FoundationDB.
> As we build our project in Rust, we would like to use the apache_avro crate,
> but some behaviors prevent us to be completely happy.
> The `append_ser` method takes a Serializable data and return bytes.
> But it turned out that the blob contains both the avro serialized data and
> the header with the complete schema avro encoded iteself.
> As we are planning to store the record schema in the database, and make the
> record refer to it thanks to the schema fingerprint. We don't need the full
> Object Container File format.
> Our idea, instead of rely on `append_ser`, is to use the `let avro_value =
> data.serialize(&mut serializer)` then get the bytes with
> ```
> to_avro_datum(&schema, avro_value)?
> ```
> But as the `apache_avro::ser` nor `apachec_avro::de` aren't public, I can't
> access from the outside of the crate to the `apacheche_avro::ser::Serializer`
> and `apacheche_avro::de::DDeserializer`.
> We need the avro_value, because we want to walk the AST.
> Can you open in `lib.rs` the serde modules ?
> ```rust
> mod codec;
> pub mod de;
> // ...
> pub mod ser;
> mod util;
> mod writer;
> ```
> Thanks :)
