Expand description
Defines memory-related functions, such as allocate/deallocate/reallocate memory regions, cache and allocation alignments.
Constants
Cache and allocation multiple alignment size
Traits
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
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
.
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
.
