Struct Task 

pub struct Task { /* private fields */ }

Implementations

impl Task

pub fn new(range: Range<u64>) -> Self

pub fn get(&self) -> Range<u64>

pub fn set(&self, range: Range<u64>)

pub fn start(&self) -> u64

pub fn set_start(&self, start: u64) -> Result<(), RangeError>

当 start > end 时返回 RangeError

pub fn fetch_add_start(&self, value: u64) -> Result<u64, RangeError>

1. 当 start + value 溢出时返回 RangeError
2. 当 start + value > end 时返回 RangeError

pub fn end(&self) -> u64

pub fn set_end(&self, end: u64) -> Result<(), RangeError>

当 end < start 时返回 RangeError

pub fn fetch_add_end(&self, value: u64) -> Result<u64, RangeError>

当 end + value 溢出时返回 RangeError

pub fn remain(&self) -> u64

pub fn split_two(&self) -> Result<Option<Range<u64>>, RangeError>

1. 当 start > end 时返回 RangeError
2. 当 remain < 2 时返回 None 并且不会修改自己

pub fn take(&self) -> Option<Range<u64>>

Trait Implementations

impl Clone for Task

fn clone(&self) -> Task

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Task

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

Formats the value using the given formatter.

impl From<&Range<u64>> for Task

fn from(value: &Range<u64>) -> Self

Converts to this type from the input type.

impl Ord for Task

fn cmp(&self, other: &Self) -> 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 Task

fn eq(&self, other: &Self) -> 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 Task

fn partial_cmp(&self, other: &Self) -> 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.
