Module polars_core::chunked_array::builder::alloc

Defines memory-related functions, such as allocate/deallocate/reallocate memory regions, cache and allocation alignments.

Constants

ALIGNMENT

Cache and allocation multiple alignment size

Statics

ALLOCATIONS

Traits

NativeType

A type that Rust’s custom allocator knows how to allocate and deallocate. This is implemented for all Arrow’s physical types whose in-memory representation matches Rust’s physical types. Consider this trait sealed.

Functions

allocate_aligned	Allocates a cache-aligned memory region of size bytes with uninitialized values. This is more performant than using allocate_aligned_zeroed when all bytes will have an unknown or non-zero value and is semantically similar to malloc.
allocate_aligned_zeroed	Allocates a cache-aligned memory region of size bytes with 0 on all of them. This is more performant than using allocate_aligned and setting all bytes to zero and is semantically similar to calloc.
free_aligned⚠	Safety
reallocate⚠	Safety
