VRAM Allocator

All GPU buffer and texture allocations route through the device's internal allocator (pools call Device::alloc_*). Clients obtain bytes via RetainedPool / TransientPool; the allocator itself is not a public customization point.

Allocation Policy (Tracking and Budget)

Install a BudgetPolicy to track live GPU bytes and optionally enforce a cap:

#![allow(unused)]
fn main() {
use goldy::BudgetPolicy;
use std::sync::Arc;

let policy = Arc::new(BudgetPolicy::with_budget(512 * 1024 * 1024)); // 512 MiB
device.ensure_allocation_policy(policy)?;

println!("GPU memory in use: {} bytes", device.tracked_vram_bytes());
}

Use BudgetPolicy::new() when you only need telemetry without a hard budget.

Relationship to pools

• RetainedPool / TransientPool — recycling policy (when deeds and leases may be reissued after GPU retirement).
• Device allocator + BudgetPolicy — provenance and optional byte budget.

Both pools allocate through the device, so an installed BudgetPolicy covers retained and transient parcels automatically.
