5.7. Packed boolean array

The BOOL_ARRAY module provides a compact boolean array implementation using bit-packing. Each boolean value uses a single bit instead of a byte, providing an 8x memory reduction compared to array<bool>.

All functions and symbols are in “bool_array” module, use require to get access to it.

5.7.1. Structures

bool_array.BoolArray

A dynamic array of booleans, stored as bits.

BoolArray.finalize()

Releases the memory used by the BoolArray.

BoolArray.[](index: int): bool
