mbrobbel opened a new pull request, #5623:
URL: https://github.com/apache/arrow-rs/pull/5623
# Which issue does this PR close?
Closes #5613.
# Rationale for this change
It came up in #5585 that the `UnionArray` constructors are a bit odd when
compared to the other array constructors.
# What changes are included in this PR?
## `UnionArray::try_new` and `UnionArray::new_unchecked`
Changed arguments:
From: `field_type_ids: &[i8], type_ids: Buffer, value_offsets:
Option<Buffer>, child_arrays: Vec<(Field, ArrayRef)>`
To: `fields: UnionFields, type_ids: ScalarBuffer<i8>, offsets:
Option<ScalarBuffer<i32>>, children: Vec<ArrayRef>`.
The order of `children` arrays must match the order of fields in the
`UnionFields`.
The validation in `try_new` is a bit more strict.
## `UnionBuilder`
It now uses a `BTreeMap` instead of a `HashMap` internally to get sorted
iteration.
# Are there any user-facing changes?
This is a breaking change that changes the `UnionArray` constructors.
