Trait BlockRead 

pub trait BlockRead: Send + Sync {
    // Required methods
    fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<()>;
    fn size_bytes(&self) -> u64;
}

Read-only random-access block device.

Required Methods

fn read_at(&self, offset: u64, buf: &mut [u8]) -> Result<()>

Read exactly buf.len() bytes starting at offset (bytes from the start of the device).

fn size_bytes(&self) -> u64

Total device size in bytes. Used for bounds checks.
