Struct Sd 

pub struct Sd<'d> { /* private fields */ }

An initialised microSD card.

Implementations

impl<'d> Sd<'d>

pub fn set_writable(&mut self, writable: bool)

Allows (or forbids) writes. Decide before handing the card to a VolumeManager; with writes forbidden, FAT bookkeeping writes fail harmlessly and reads keep working.

pub fn is_writable(&self) -> bool

Whether writes are allowed.

pub fn size_bytes(&self) -> Result<u64, Error>

Card capacity in bytes.

pub fn card_type(&self) -> Option<CardType>

Card generation (SD1, SD2, SDHC/SDXC).

pub fn card(&self) -> &Card<'d>

The underlying driver. Writes through it bypass the read-only guard.

Trait Implementations

impl BlockDevice for Sd<'_>

type Error = Error

The errors that the BlockDevice can return. Must be debug formattable.

fn read(&self, blocks: &mut [Block], start: BlockIdx) -> Result<(), Error>

Read one or more blocks, starting at the given block index.

fn write(&self, blocks: &[Block], start: BlockIdx) -> Result<(), Error>

Write one or more blocks, starting at the given block index.

fn num_blocks(&self) -> Result<BlockCount, Error>

Determine how many blocks this device can hold.
