Struct DeviceStats 

pub struct DeviceStats {
    pub devid: u64,
    pub write_errs: u64,
    pub read_errs: u64,
    pub flush_errs: u64,
    pub corruption_errs: u64,
    pub generation_errs: u64,
}

Per-device I/O error statistics, as returned by BTRFS_IOC_GET_DEV_STATS.

Fields

devid: u64

Device ID these stats belong to.

write_errs: u64

Number of write I/O errors (EIO/EREMOTEIO from lower layers).

read_errs: u64

Number of read I/O errors (EIO/EREMOTEIO from lower layers).

flush_errs: u64

Number of flush I/O errors (EIO/EREMOTEIO from lower layers).

corruption_errs: u64

Number of checksum or bytenr corruption errors detected on read.

generation_errs: u64

Number of generation errors (blocks not written where expected).

Implementations

impl DeviceStats

pub fn total_errs(&self) -> u64

Sum of all error counters.

pub fn is_clean(&self) -> bool

Returns true if every counter is zero.

Trait Implementations

impl Clone for DeviceStats

fn clone(&self) -> DeviceStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DeviceStats

fn default() -> DeviceStats

Returns the “default value” for a type.

impl PartialEq for DeviceStats

fn eq(&self, other: &DeviceStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
