Function applyWeightBuffer

applyWeightBuffer(weight: Weight, options?: { percent?: number }): Weight
Apply a safety buffer to weight estimates from a dry-run result.

Dry-run weight estimates reflect the exact execution cost at the time of simulation. On-chain conditions can change between dry-run and actual submission (storage growth, state changes by other transactions), so a buffer prevents unexpected OutOfGas failures.

The default 25% buffer matches the convention used across Polkadot ecosystem tooling.
Parameters
- weight: Weight
  The weight_required from a ReviveApi.call or ReviveApi.eth_transact dry-run.
- Optionaloptions: { percent?: number }
  Override the buffer percentage (default: 25%).
Returns Weight
A new weight with both components scaled up.
Example: Basic usage with ReviveApi dry-run:
```
const dryRun = await api.apis.ReviveApi.call(origin, dest, value, undefined, undefined, data);

const tx = api.tx.Revive.call({
  dest, value, data,
  weight_limit: applyWeightBuffer(dryRun.weight_required),
  storage_deposit_limit: dryRun.storage_deposit.value,
});
```
Example: Custom buffer for latency-sensitive operations:
```
applyWeightBuffer(dryRun.weight_required, { percent: 50 });
```
