Yannick Guern created AVRO-3804:
-----------------------------------
Summary: Open the visibility of serde implementation
Key: AVRO-3804
URL: https://issues.apache.org/jira/browse/AVRO-3804
Project: Apache Avro
Issue Type: Improvement
Components: rust
Reporter: Yannick Guern
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 :)
