class FakeBlockDevice
Defined at line 33 of file ../../src/storage/lib/block_client/cpp/fake_block_device.h
A fake device implementing (most of) the BlockDevice interface on top of an in-memory VMO
representing the device. This allows clients of the BlockDevice interface to test against this
fake in-process instead of relying on a real block device.
This device also supports pausing processing FIFO transactions to allow tests to emulate slow
devices or validate behavior in intermediate states.
This class is thread-safe.
This class is not movable or copyable.
Public Methods
void FakeBlockDevice (const Config & )Defined at line 19 of file ../../src/storage/lib/block_client/cpp/fake_block_device.cc
zx::result<zx::vmo> VmoChildReference ()Returns a VMO child reference of the block device.
Defined at line 31 of file ../../src/storage/lib/block_client/cpp/fake_block_device.cc
void Pause ()When paused, this device will make FIFO operations block until Resume() is called. The device
is in the Resume() state by default.

void SetWriteBlockLimit (uint64_t limit)Sets the number of blocks which may be written to the block device. Once |limit| is reached,
all following operations will return ZX_ERR_IO.
May be "std::nullopt" to allow an unlimited count of blocks.
