Module transform

Low-level array data abstractions.

Provides utilities for creating, manipulating, and converting Arrow arrays made of primitive types, strings, and nested types.

Modules

• fixed_binary 🔒
• fixed_size_list 🔒
• list 🔒
• null 🔒
• primitive 🔒

Structs

• MutableArrayData
  Efficiently create an ArrayData from one or more existing ArrayDatas by copying chunks.
• _MutableArrayData 🔒
  A mutable ArrayData that knows how to freeze itself into an ArrayData. This is just a data container.

Enums

• Capacities
  Define capacities to pre-allocate for child data or data buffers.

Functions

• build_extend 🔒
• build_extend_dictionary 🔒
  Builds an extend that adds offset to the source primitive Additionally validates that max fits into the the underlying primitive returning None if not
• build_extend_null_bits 🔒
• build_extend_nulls 🔒
• build_extend_view 🔒
  Builds an extend that adds buffer_offset to any buffer indices encountered
