> [Rust] New RecordBatch requires exact match of Data Types

> Key: ARROW-10656
> URL: https://issues.apache.org/jira/browse/ARROW-10656
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust
> Reporter: Christoph Schulze

> Time Spent: 8h 20m
> Remaining Estimate: 0h
>
> When instanciating a new RecordBatch with {{try_new()}}, the data types of
> columns are checked to match their corresponding fields in the schema with
> {{==}}. The {{==}} operator will consider all attribues of the two data types
> and compare strictly if all values are equal. However, a code comment above
> this comparison indicates _[1]_:
> ?? list types can have different names, but we only need the data types to be
> the same??
> Since ARROW-10261 ([PR|https://github.com/apache/arrow/pull/8608]) was merged
> lists contain a {{Field}} instead of just a {{DataType}}. Therefore, the
> values of this field are striclty compared. This behavior contradicts the
> comment.
> *Solution*
>
> The data type comparison in {{try_new()}} should be changed into only
> matching data types, including the nested ones, but leaving out other values.
