gc

Manual control of the garbage collector for benchmarks and tight-loop tuning.

Import

import gc

Functions

gc.collect()

Trigger a garbage collection cycle immediately.

gc.disable()

Disable automatic collection. Manual gc.collect() calls still work.

gc.enable()

Re-enable automatic collection after a gc.disable().

gc.stats() -> map

Return a map of collection counters and current tracked-object counts.

gc.set_threshold(n: int)

Set the allocation count threshold that triggers a young-generation collection.

Examples

import gc

-- check stats before
let before = gc.stats()
println(before)

-- disable, allocate a bunch, then collect manually
gc.disable()
let big = []
for i in 0..10000 { big.push(i) }
gc.collect()
gc.enable()

let after_stats = gc.stats()
println(after_stats)
