Module mem 

Memory management utilities — port of ojph_mem.h/cpp.

Provides aligned allocation, line buffers, and arena-style allocators that mirror the C++ OpenJPH memory model.

Structs

AlignedVec

A heap-allocated, contiguously-stored buffer with a guaranteed minimum byte alignment (defaults to BYTE_ALIGNMENT = 64, suitable for AVX-512).

CodedLists

A node in a singly-linked list of coded data buffers — port of coded_lists.

LiftingBuf

A line buffer reference used during wavelet lifting.

LineBuf

A single line (row) of sample data used throughout the wavelet and coding pipeline — port of the C++ line_buf.

MemElasticAllocator

An arena-style allocator that grows by appending large chunks.

MemFixedAllocator

A two-phase bump allocator for fixed-size, aligned sub-regions.

Enums

LineBufData

Discriminated pointer to the actual sample data in a LineBuf.

Constants

LFT_32BIT

Flag: buffer elements are 32 bits wide.

LFT_64BIT

Flag: buffer elements are 64 bits wide.

LFT_INTEGER

Flag: buffer elements are integers (as opposed to float).

LFT_SIZE_MASK

Mask that isolates the element-size field.

LFT_UNDEFINED

Flag: buffer type is undefined / not yet allocated.
