LeaseGuard

memory_budget

Struct LeaseGuard 

Source 
pub struct LeaseGuard { /* private fields */ }
Expand description

Active short-term reservation against the budget.

While alive, the effective per-cache target is reduced by bytes(). The reduction is released when the guard is dropped.

Issued by MemoryBudget::lease. The guard owns the shared accounting state until release, even when the public budget handle has been dropped. It never releases a reservation merely because work moved to another task or queue.
