Struct Room 

pub struct Room { /* private fields */ }

The trigger’s threshold and what growth steps may still add to reserved memory before the budget is reached. Every arena and the value heap charge their growth steps here; a step past the budget zeroes the threshold, so the next safepoint collects.

Implementations

impl Room

pub const fn unbounded() -> Room

No budget and no trigger (GcPolicy::Manual, the arenas’ tests).

pub fn new(left: usize, threshold: usize) -> Room

left bytes of growth below the budget and threshold nominal bytes before the next collection.

pub fn take(&mut self, bytes: usize)

Charges a growth step of bytes.

pub fn threshold(&self) -> usize
