Struct ExtCsd 

pub struct ExtCsd { /* private fields */ }

Lightly typed view over the 512-byte EXT_CSD payload.

Holding the full register lets later phases of the driver read fields that aren’t needed today (e.g. BOOT_PARTITION_SIZE, RPMB_SIZE_MULT, PARTITION_SETTING_COMPLETED) without having to re-issue CMD8.

Implementations

impl ExtCsd

pub fn from_bytes(raw: [u8; 512]) -> Self

pub fn as_bytes(&self) -> &[u8; 512]

Raw 512-byte payload (immutable view) for fields the typed API hasn’t grown to cover yet.

pub fn sector_count(&self) -> Option<u32>

Authoritative sector count for cards ≥ 2 GB. Returns None when the field is zero, which means “use the legacy CSD C_SIZE instead” (small cards).

pub fn device_type(&self) -> DeviceType

pub fn bus_width(&self) -> MmcBusWidth

pub fn timing(&self) -> MmcTiming
