Accepts mutations from a transaction that belong to this collection and persists them. This should be called in your transaction's mutationFn to persist local-only data.

PendingMutation <Record<string, unknown>, OperationType , Collection <Record<string, unknown>, any, any, any, any>>[]

#### Returns

void

#### Example

ts

const localData = createCollection(localOnlyCollectionOptions({...}))

const tx = createTransaction({
  mutationFn: async ({ transaction }) => {
    // Make API call first
    await api.save(...)
    // Then persist local-only mutations after success
    localData.utils.acceptMutations(transaction)
  }
})


const localData = createCollection(localOnlyCollectionOptions({...}))

const tx = createTransaction({
  mutationFn: async ({ transaction }) => {
    // Make API call first
    await api.save(...)
    // Then persist local-only mutations after success
    localData.utils.acceptMutations(transaction)
  }
})
