Struct rat_widget::textarea::core::TextRange

pub struct TextRange {
    pub start: (usize, usize),
    pub end: (usize, usize),
}

Range for text ranges.

Fields

start: (usize, usize)

end: (usize, usize)

Implementations

impl TextRange

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

New text range.

Panic Panics if start > end.

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

Start position

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

End position

pub fn is_empty(&self) -> bool

Empty range

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

Range contains the given position.

pub fn contains_range(&self, range: TextRange) -> bool

Range contains the other range.

pub fn ordering(&self, pos: (usize, usize)) -> Ordering

What place is the range respective to the given position.

pub fn ordering_inclusive(&self, pos: (usize, usize)) -> Ordering

What place is the range respective to the given position. This one includes the range.end.

pub fn expand_all(&self, it: Skip<IterMut<'_, (TextRange, usize)>>)

Modify all positions in place.

pub fn shrink_all(&self, it: Skip<IterMut<'_, (TextRange, usize)>>)

Modify all positions in place.

pub fn expand(&self, pos: (usize, usize)) -> (usize, usize)

Return the modified position, as if this range expanded from its start to its full expansion.

pub fn shrink(&self, pos: (usize, usize)) -> (usize, usize)

Return the modified position, if this range would shrink to nothing.

Trait Implementations

impl Clone for TextRange

fn clone(&self) -> TextRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextRange

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

Formats the value using the given formatter.

impl Default for TextRange

fn default() -> TextRange

Returns the “default value” for a type.

impl Ord for TextRange

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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TextRange

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

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

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.
