Struct TextRange

pub struct TextRange { /* private fields */ }

A range in the text, represented as a pair of TextUnits.

Panics

Slicing a &str with TextRange panics if the result is not a valid utf8 string.

Implementations

impl TextRange

pub fn from_to(from: TextUnit, to: TextUnit) -> TextRange

pub fn start(&self) -> TextUnit

The inclusive start of this range

pub fn end(&self) -> TextUnit

The exclusive end of this range

pub fn len(&self) -> TextUnit

The length of this range

pub fn is_empty(&self) -> bool

Is this range empty of any content?

pub fn is_subrange(&self, other: &TextRange) -> bool

pub fn intersection(&self, other: &TextRange) -> Option<TextRange>

The resulting type after applying the + operator.

fn add(self, rhs: &'a TextUnit) -> TextRange

Performs the + operation.

impl<'a> Add<TextUnit> for &'a TextRange

type Output = TextRange

The resulting type after applying the + operator.

fn add(self, rhs: TextUnit) -> TextRange

Performs the + operation.

impl Add<TextUnit> for TextRange

type Output = TextRange

The resulting type after applying the + operator.

fn add(self, rhs: TextUnit) -> TextRange

Performs the + operation.

impl<'a> AddAssign<&'a TextUnit> for TextRange

fn add_assign(&mut self, rhs: &'a TextUnit)

Performs the += operation.

impl AddAssign<TextUnit> for TextRange

fn add_assign(&mut self, rhs: TextUnit)

Performs the += operation.

impl Clone for TextRange

fn clone(&self) -> TextRange

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Display for TextRange

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

Formats the value using the given formatter.

impl Hash for TextRange

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Index<TextRange> for str

type Output = str

The returned type after indexing.

fn index(&self, index: TextRange) -> &str

Performs the indexing (container[index]) operation.

impl PartialEq for TextRange

fn eq(&self, other: &TextRange) -> 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 RangeBounds<TextUnit> for TextRange

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

Start index bound.

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

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.
