Trait BlockDevice 

pub trait BlockDevice {
    // Required methods
    fn config(&self) -> Config;
    fn read(&self, block: u32, off: usize, out: &mut [u8]) -> Result<()>;
    fn prog(&mut self, block: u32, off: usize, data: &[u8]) -> Result<()>;
    fn erase(&mut self, block: u32) -> Result<()>;

    // Provided method
    fn sync(&mut self) -> Result<()> { ... }
}

Minimal synchronous block-device interface for littlefs experiments.

The trait deliberately mirrors littlefs’s block-level vocabulary instead of exposing a raw byte slice. read and prog operate inside one logical block, erase resets an entire block, and sync gives later writable backends a place to flush durable state.

Required Methods

fn config(&self) -> Config

fn read(&self, block: u32, off: usize, out: &mut [u8]) -> Result<()>

fn prog(&mut self, block: u32, off: usize, data: &[u8]) -> Result<()>

fn erase(&mut self, block: u32) -> Result<()>

Provided Methods

fn sync(&mut self) -> Result<()>
