Struct Handle

pub struct Handle {
    pub token: Token,
    pub desc: Description,
    pub user_defined_desc: Option<*const ()>,
    pub data: *const (),
}

File description handle. created by implementator.

Fields

token: Token

Token associated with this handle object

desc: Description

File description variant

user_defined_desc: Option<*const ()>

Additional user-defined fd metadata

data: *const ()

user-defined context data for this file handle.

Implementations

impl Handle

pub fn new( desc: Description, user_defined_desc: Option<*const ()>, token: Option<Token>, data: *const (), ) -> Self

Create new file handle.

pub fn drop_as<T>(self)

Drop handle context data with special type.

pub fn expect(&self, desc: Description) -> Result<()>

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate 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<T> From<(Description, T)> for Handle

fn from(value: (Description, T)) -> Self

Converts to this type from the input type.

impl<UDDESC, T> From<(Description, UDDESC, T)> for Handle

fn from(value: (Description, UDDESC, T)) -> Self

Converts to this type from the input type.

impl<UDDESC, T> From<(Description, UDDESC, Token, T)> for Handle

fn from(value: (Description, UDDESC, Token, T)) -> Self

Converts to this type from the input type.

impl<T> From<Handle> for TypedHandle<T>

fn from(value: Handle) -> Self

Converts to this type from the input type.

impl Hash for Handle

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 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,

Restrict a value to a certain interval.

impl PartialEq for Handle

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

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.
