Public Methods

void AllocatorStorage ()

void AllocatorStorage (const AllocatorStorage & )

zx::result<> AttachVmo (const zx::vmo & vmo, storage::OwnedVmoid * vmoid)
void Load (fs::BufferedOperationsBuilder * builder, storage::BlockBuffer * data)

Loads data from disk into |data| using |builder|.

The implementation of this class is expected to use the builder to complete

the request, which means that it should provide the type of data expected

by the builder. Specifically, all that should be needed from |data| on host

code is access to a raw pointer, and all that should be needed on Fuchsia

code is the vmoid that identifies the buffer.

For more details consult the BufferedOperationsBuilder documentation.

zx::result<> Extend (PendingWork * transaction, WriteData data, GrowMapCallback grow_map)

Extend the on-disk extent containing map_.

zx::result<> Extend (PendingWork * transaction, WriteData data, GrowMapCallback grow_map)

Extend the on-disk extent containing map_.

uint32_t PoolAvailable ()

Returns the number of unallocated elements.

uint32_t PoolTotal ()

Returns the total number of elements.

uint32_t PoolBlocks ()

The number of blocks necessary to store |PoolTotal()| elements.

void PersistRange (PendingWork * transaction, WriteData data, size_t index, size_t count)

Persists the map at range |index| - |index + count|.

void PersistRange (PendingWork * transaction, WriteData data, size_t index, size_t count)

Persists the map at range |index| - |index + count|.

void PersistAllocate (PendingWork * transaction, size_t count)

Marks |count| elements allocated and persists the latest data.

void PersistRelease (PendingWork * transaction, size_t count)

Marks |count| elements released and persists the latest data.
