class BaseBufferView

Defined at line 62 of file ../../src/storage/minfs/buffer_view.h

BaseBufferView and BufferView are views of a buffer, a contiguous range in memory. It can be

mutable or immutable. It keeps track of the use of mutable methods to record whether or not it is

dirty. A flusher object is provided for flushing the buffer and is called via the Flush method if

the buffer is deemed dirty. If no flusher is provided, the view is considered immutable. The

underlying buffer can be memory, or it can be a BlockBuffer which we specialise for, in case

BlockBuffer is resized, in which case its mapped address can change.

zx::result<> Flush ()

Does nothing if the buffer is not dirty. The buffer is always marked clean after calling flush;

it is up to the caller to handle errors appropriately.
