[jira] [Created] (ARROW-9519) [Rust] Improve error message when getting a field by name from schema

Jorge created ARROW-9519:
----------------------------

             Summary: [Rust] Improve error message when getting a field by name from schema
                 Key: ARROW-9519
                 URL: https://issues.apache.org/jira/browse/ARROW-9519
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust
            Reporter: Jorge
            Assignee: Jorge


Currently, when a name that does not exist on the Schema is passed to {{Schema::index_of}}, the error message is just the name itself. This makes it a bit difficult to debug.

 

I propose that we change the that error message to something like

{{Unable to get field named "nickname". Valid fields: ["first_name", "last_name", "address"]}}

to make it easier to understand.
