Struct Disktest

pub struct Disktest { /* private fields */ }

Disktest core.

Implementations

impl Disktest

pub const UNLIMITED: u64 = 18_446_744_073_709_551_615u64

Unlimited max_bytes.

pub fn new( algorithm: DtStreamType, seed: &[u8], round_id: u64, invert_pattern: bool, nr_threads: usize, quiet_level: DisktestQuiet, abort: Option<Arc<AtomicBool>>, ) -> Disktest

Create a new Disktest instance.

Parameters:

• algorithm: Select the algorithm to generate the random data stream that is written to disk. If unsure, use Default::default().
• seed: The seed for the random data stream generator.
• round_id: The disk test round. Every round gets a unique data stream. If unsure, use 0 (first round).
• invert_pattern: Bitwise invert the random data stream. If unsure, use false (don’t invert).
• nr_threads: The number of threads to spawn when generating the random data stream. The special value 0 means: Use all CPUs available in the system. If unsure, use 1 (One CPU).
• quiet_level: The console verbosity of the Disktest code. See DisktestQuiet.
• abort: If this optional flag is set to true (e.g. by another thread) the Disktest process will abort as soon as possible. If unsure, use None.

pub fn write( &mut self, file: DisktestFile, seek: u64, max_bytes: u64, ) -> Result<u64>

Run disktest in write mode.

pub fn verify( &mut self, file: DisktestFile, seek: u64, max_bytes: u64, ) -> Result<u64>

Run disktest in verify mode.
