Struct Range

pub struct Range<T> {
    pub start: T,
    pub end: T,
}

Fields

start: T

end: T

Implementations

impl<T: PartialOrd + Debug> Range<T>

pub fn new(start: T, end: T) -> Self

impl<T: PartialOrd> Range<T>

pub fn is_empty(&self) -> bool

pub fn contains<U>(&self, item: &U) -> bool

where T: PartialOrd<U>, U: PartialOrd<T> + ?Sized,

impl<T: NumericRangeBound> Range<T>

pub fn len(&self) -> T

pub fn pop_front(&mut self) -> Option<T>

Shrink the length of this range by one element from the front, returning the first item in the range.

pub fn pop_back(&mut self) -> Option<T>

Shrink the length of this range by one element from the end, returning the last item in the range.

pub fn shrink_front(&mut self, n: T)

Shrink this range by advancing the start of the range n elements, i.e. (start + n)..end

NOTE: This function will saturate to self.end to ensure the range remains valid.

pub fn truncate(&mut self, new_len: T)

Truncate this range such that it’s length is new_len, i.e. start..(start + new_len)

This effectively drops elements from the back of the range;

NOTE: This function will panic if new_len is greater than the current length

Trait Implementations

impl<T: Clone> Clone for Range<T>

fn clone(&self) -> Self

Converts to this type from the input type.

impl<T> Index<Range<usize>> for [T]

type Output = [T]

The returned type after indexing.

fn index(&self, idx: Range<usize>) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<T> IndexMut<Range<usize>> for [T]

fn index_mut(&mut self, idx: Range<usize>) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl<T: Ord> Ord for Range<T>

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<T: PartialEq> PartialEq for Range<T>

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<T: PartialOrd> PartialOrd for Range<T>

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.

impl<T> RangeBounds<T> for Range<T>

fn start_bound(&self) -> Bound<&T>

Start index bound.

fn end_bound(&self) -> Bound<&T>

End index bound.

fn contains<U>(&self, item: &U) -> bool

where T: PartialOrd<U>, U: PartialOrd<T> + ?Sized,

Returns true if item is contained in the range.

fn is_empty(&self) -> bool

where T: PartialOrd,

🔬This is a nightly-only experimental API. (range_bounds_is_empty)

Returns true if the range contains no items. One-sided ranges (RangeFrom, etc) always return false.
