Struct MemoryBlockDevice 

pub struct MemoryBlockDevice { /* private fields */ }

In-memory NOR-flash block device used by tests and early integrations.

Blocks start erased to 0xff. Programming uses old & new, so accidental attempts to turn a programmed zero bit back into one are visible in the stored bytes just as they would be on NOR flash. This is intentionally a real block device implementation for tests, not a mock of filesystem behavior.

Implementations

impl MemoryBlockDevice

pub fn new_erased(cfg: Config) -> Result<Self>

pub fn from_bytes(cfg: Config, bytes: &[u8]) -> Result<Self>

pub fn as_bytes(&self) -> &[u8]
