Santiago Fraire Willemoes updated AVRO-4055:
--------------------------------------------
Description:
*Current state*
Rust parses the following schema correctly, without raising any errors:
{code}
{
"type": "record",
"name": "SampleSchema",
"fields": [
{
"name": "order",
"type": "record",
"fields": [
{
"name": "order_number",
"type": ["null", "string"],
"default": null
},
{ "name": "order_date", "type": "string" }
]
}
]
}
{code}
*Desired state*
Rust returns an error with the previous schema
*Correct schema sample*
Sample code:
{code}
use apache_avro::Schema;
let raw_schema = r#"
{
"type": "record",
"name": "SampleSchema",
"fields": [
{
"name": "order",
"type": "record",
"fields": [
{
"name": "order_number",
"type": ["null", "string"],
"default": null
},
{ "name": "order_date", "type": "string" }
]
}
]
}
"#;
// if the schema is not valid, this function will return an error
let schema = Schema::parse_str(raw_schema).unwrap();
// schemas can be printed for debugging
println!("{:?}", schema);
{code}
Why is this important? Other tools like in Java are not able to parse this
schema, making compatibility between different languages harder.
We've had issues using `avro-tools` to build the jars.
I can try to fix it, let me know if you want me to send a PR.

Parsing a schema like this should be invalid on rust, but rust parses the
schema without raising errors:
