Struct ioprio::Priority

pub struct Priority { /* fields omitted */ }

An I/O priority, either associated with a class and per-class data, or the standard priority.

Implementations

impl Priority

pub fn new(class: Class) -> Self

Construct a new I/O priority value, from the priority class and per-class level.

pub fn class(self) -> Option<Class>

Retrieve the class, if any such class was set.

pub const fn standard() -> Self

Get the value for the default priority, with the inner value of zero.

pub const fn inner(self) -> u16

Get the inner I/O priority mask, which can be set in several interfaces, including io_uring, AIO, and the regular ioprio_* syscalls.

pub const fn from_inner(inner: u16) -> Self

Construct an I/O priority from the inner value.

Note that it is up to the caller to ensure the validity of the mask.

Trait Implementations

impl Clone for Priority

fn clone(&self) -> Priority

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Priority

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

Formats the value using the given formatter.

impl Default for Priority

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Priority

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Priority> for Priority

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Priority> for Priority

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

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

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

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

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

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