Expand description

Tracks approximate memory usage for budget enforcement.

Fields§

§variable_count: usize

Number of scalar variables (excluding internal markers).

§variable_bytes: usize

Total bytes in variable keys + values.

§array_entries: usize

Total entries across all arrays (indexed + associative).

§function_count: usize

Number of function definitions.

§function_body_bytes: usize

Total bytes in function bodies.
