joseph-isaacs opened a new issue, #6467: URL: https://github.com/apache/arrow-rs/issues/6467
**Describe the bug** <!-- A clear and concise description of what the bug is. --> Two lists should be equal, irrespective of this field name, which is an implementation detail. In the arrow [C data interface spec](https://arrow.apache.org/docs/format/CDataInterface.html), the list data type format string is defined excluding names from list types, however arrow-rs defines a them as `List(FieldRef)` and defines equality structurally (using `derive(Eq)`) **To Reproduce** <!-- Steps to reproduce the behavior: --> ```rust let s1 = Field::new_list_field(DataType::Int32, true); let s2 = Field::new("abc", DataType::Int32, true); assert_eq!(f1, f2); ``` **Expected behavior** <!-- A clear and concise description of what you expected to happen. --> I expect that these two schemas `s1` and `s2` should be equal see the C ABI schema [here](https://arrow.apache.org/docs/format/CDataInterface.html#examples), "A list<uint64> array has format string `+l`, and its single child has format string `L.`" **Additional context** <!-- Add any other context about the problem here. --> This has caused a problem when writing a parquet file using pyarrow and reading it using arrow-rs -- This is an automated message from the Apache Git Service.
