Crate sparse_mem 

Functions

alignment

Alignment requirement for the sparse array. Report 4 just for the benefit of values

allocate^⚠

Allocate a new ID and generation.

element_count^⚠

Get current element count

element_size^⚠

Get current element size

generation_ptr_const^⚠

get_value_ptr^⚠

Get value pointer for a valid handle Returns None if the handle is invalid

id_to_slot_ptr^⚠

Get a pointer to the id_to_slot array (forward lookup)

id_to_slot_ptr_const^⚠

init^⚠

Initialize the sparse array to memory specified by the raw memory pointer. base must point to a region of at least layout_size(capacity, element_size) bytes.

insert^⚠

Insert raw bytes at handle id

insert_if_alive^⚠

Safe wrapper for insert that validates the handle Insert raw bytes at handle id, but only if the handle is valid Returns true if successful, false if the handle is invalid

is_alive^⚠

Check handle validity

layout_size

Compute total bytes needed in memory for a sparse array. Used for code generator to know how much space to reserve.

remove^⚠

Remove by handle; frees slot and bumps generation. Returns false on mismatching generations.

slot_to_id_ptr^⚠

Get a pointer to the slot_to_id array (reverse lookup)

slot_to_id_ptr_const^⚠

Get a pointer to the slot_to_id array (reverse lookup)

values_offset

Compute offset of values region (values are aligned to 8 bytes)
