Enum IopsCounter 

pub enum IopsCounter {
    PerIo,
    PerIoSize(NonZeroUsize),
}

Device iops counter.

Variants

PerIo

Count 1 iops for each read/write.

PerIoSize(NonZeroUsize)

Count 1 iops for each read/write with the size of the i/o.

Implementations

impl IopsCounter

pub fn per_io() -> Self

Create a new iops counter that count 1 iops for each io.

pub fn per_io_size(io_size: usize) -> Self

Create a new iops counter that count 1 iops for every io size in bytes among ios.

NOTE: io_size must NOT be zero.

pub fn count(&self, bytes: usize) -> usize

Count io(s) by io size in bytes.

Trait Implementations

impl Clone for IopsCounter

fn clone(&self) -> IopsCounter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IopsCounter

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

Formats the value using the given formatter.

impl Default for IopsCounter

fn default() -> IopsCounter

Returns the “default value” for a type.

impl Display for IopsCounter

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

Formats the value using the given formatter.

impl FromStr for IopsCounter

type Err = Error

The associated error which can be returned from parsing.

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

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

impl PartialEq for IopsCounter

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