read_ticks: u64

Returns the total wait time for read requests.

write_ios: u64

Returns the number of write I/Os processed.

write_merges: u64

Returns the number of write I/Os merged with in-queue I/O.

write_sectors: u64

Returns the number of sectors written.

write_ticks: u64

Returns the total wait time for write requests.

in_flight: u64

Implementations

impl Stat

pub const fn read_bytes(&self) -> u64

Returns the total amount of bytes read (assuming 512 byte sectors).

pub const fn write_bytes(&self) -> u64

Returns the total amount of bytes written (assuming 512 byte sectors).

Trait Implementations

impl Add for Stat

type Output = Stat

The resulting type after applying the + operator.

fn add(self, other: Self) -> Self

Performs the + operation.

impl AddAssign for Stat

fn add_assign(&mut self, other: Self)

Performs the += operation.

impl Clone for Stat

fn clone(&self) -> Stat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stat

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

Formats the value using the given formatter.

impl Default for Stat

fn default() -> Stat

Returns the “default value” for a type.

impl FromStr for Stat

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for Stat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Stat

fn cmp(&self, other: &Stat) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Stat

fn eq(&self, other: &Stat) -> 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.

impl PartialOrd for Stat

fn partial_cmp(&self, other: &Stat) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
