struct ReadWriteMetadata

Defined at line 49 of file ../../src/devices/block/drivers/sdmmc/sdmmc-block-device.h

This struct is used to maintain metadata for IO while the IO is in progress: When using Banjo,

this is a hard requirement, as only object handles are passed through the call. When using FIDL,

objects can be transferred through the call. However for performance, we avoid repeatedly

creating and initializing objects.
