class FtlRawNandImageWriter
Defined at line 28 of file ../../src/storage/volume_image/ftl/ftl_raw_nand_image_writer.h
This writer provdes an adapter layer between the expected hardware page and oob size, and the
minimum requirements for the FTL.
The FTL requires a minimum number of oob bytes, if this is not met by the underlying hardware,
pages are merged, so that the oob bytes of two consecutive pages can be treated a single one.
The end result is that pages and oob size get multiplied by a factor such that min(k) such that
k * hardware_oob_size >= min FTL oob size.
Public Methods
fpromise::result<std::tuple<FtlRawNandImageWriter, RawNandOptions>, std::string> Create (const RawNandOptions & device_options, std::span<const RawNandImageFlag> flags, ImageFormat format, Writer * writer)Returns a |FtlRawNandWriter| that will translate requests from the |device_options| into
the returned |options| that are guaranteed to be valid for FTL metadata on success.

uint32_t scale_factor ()Returns a scalar describing how pages are coalesced to meet the upper layer requirements.

fpromise::result<void, std::string> Write (uint64_t offset, std::span<const uint8_t> data)On success data backing this writer is updated at [|offset|, |offset| +
|buffer.size()|] to |buffer|.
This Write method expects page data and page oob to be performed in separate calls.
On error the returned result to contains a string describing the error.
