Method set_limit

nodedb-mem/src/budget.rs:215–219

Update the limit dynamically (for rebalancing). The new limit must be >= current allocation. If it's less, the limit is set to the current allocation (no immediate eviction).

    /// The new limit must be >= current allocation. If it's less, the limit
    /// is set to the current allocation (no immediate eviction).
    pub fn set_limit(&self, new_limit: usize) {
        let allocated = self.allocated();
        let effective = new_limit.max(allocated);
        self.limit.store(effective, Ordering::Release);
    }
