Struct poplar::Handle

pub struct Handle(pub u32);

A Handle is used to represent a task’s access to a kernel object. It is allocated by the kernel and is unique to the task to which it is issued - a kernel object can have handles in multiple tasks (and the numbers will not be shared between those tasks).

pub const ZERO: Handle = _

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Handle

fn deserialize(deserializer: &mut Deserializer<'de>) -> Result<Handle>

impl Ord for Handle

fn cmp(&self, other: &Handle) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Handle

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

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

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

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

impl PartialOrd for Handle

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

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

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

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

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

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

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

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

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

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

impl Serialize for Handle

fn serialize<W>(&self, serializer: &mut Serializer<W>) -> Result<()>

where W: Writer,

impl TryFrom<usize> for Handle

type Error = TryFromIntError

The type returned in the event of a conversion error.

fn try_from(value: usize) -> Result<Self, Self::Error>

Performs the conversion.
