             Summary: [Rust] [DataFusion] Remove FunctionMeta
                 Key: ARROW-9835
                 URL: https://issues.apache.org/jira/browse/ARROW-9835
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust, Rust - DataFusion
            Reporter: Jorge


Currently, our code works as follows:

1. Declare a UDF via {{udf::ScalarFunction}}
 2. Register the UDF
 3. call {{scalar_function("name", vec![...], type)}} to use it during planning.

However, during planning, we:

1. Get the ScalarFunction by name
 2. convert it to FunctionMetadata
 3. get the ScalarFunction associated with FunctionMetadata's name

I.e. {{FunctionMetadata}} does not seem to be needed.

Goal: remove {{FunctionMetadata}} and just pass {{udf::ScalarFunction}} directly from the registry to the physical plan.
