Struct xi_rope::interval::Interval

pub struct Interval {
    pub start: usize,
    pub end: usize,
}

A fancy version of Range, representing a closed-open range; the interval [5, 7) is the set {5, 6}.

It is an invariant that start <= end. An interval where end < start is considered empty.

Fields

start: usize

end: usize

Methods

impl Interval

pub fn new(start: usize, end: usize) -> Interval

Construct a new Interval representing the range [start..end). It is an invariant that start <= end.

pub fn new_closed_open(start: usize, end: usize) -> Interval

Deprecated since 0.3.0:

all intervals are now closed_open, use Interval::new

pub fn new_open_closed(start: usize, end: usize) -> Interval

Deprecated since 0.3.0:

all intervals are now closed_open

pub fn new_closed_closed(start: usize, end: usize) -> Interval

Deprecated since 0.3.0:

all intervals are now closed_open

pub fn new_open_open(start: usize, end: usize) -> Interval

Deprecated since 0.3.0:

pub fn start(&self) -> usize

pub fn end(&self) -> usize

pub fn start_end(&self) -> (usize, usize)

pub fn is_before(&self, val: usize) -> bool

the interval is before the point (the point is after the interval)

pub fn contains(&self, val: usize) -> bool

the point is inside the interval

pub fn is_after(&self, val: usize) -> bool

the interval is after the point (the point is before the interval)

pub fn is_empty(&self) -> bool

pub fn intersect(&self, other: Interval) -> Interval

pub fn union(&self, other: Interval) -> Interval

pub fn prefix(&self, other: Interval) -> Interval

pub fn suffix(&self, other: Interval) -> Interval

pub fn translate(&self, amount: usize) -> Interval

pub fn translate_neg(&self, amount: usize) -> Interval

pub fn size(&self) -> usize
