'How to build an Apache Arrow message containing a list of structs with arrow-rs?
I'm using the arrow-rs crate (version 4.4) to declared the following schema:
Schema::new(vec![
Field::new("name", DataType::Utf8, false),
Field::new("attributes", DataType::List(
Box::new(Field::new(
"attr",
DataType::Struct(vec![
Field::new("name", DataType::Utf8, false),
Field::new("value", DataType::Utf8, false),
]),
true,
))
), true),
])
I'm struggling to find a complete example building a record batch from this type of schema containing a list of structs.
