Struct TextSpan

pub struct TextSpan {
    pub start: TextOffset,
    pub end: TextOffset,
}

A range of text offsets that form a span (like text selection).

Fields

start: TextOffset

end: TextOffset

Implementations

impl TextSpan

pub fn width(self) -> TextWidth

pub fn contains(self, other: Self) -> bool

pub fn take(self, content: &str) -> &str

pub fn n_chars(self, content: &str) -> usize

pub fn after(self) -> Self

Get the span of width 0, located right after this span.

pub fn start_only(self) -> Self

Get the span of width 0, located right at the beginning of this span.

pub fn to_str_range(&self) -> Range<usize>

Returns self.start..self.end as Range<usize>

pub fn position_in_file( self, db: &dyn FilesGroup, file: FileId, ) -> Option<TextPositionSpan>

Convert this span to a TextPositionSpan in the file.

Trait Implementations

impl Clone for TextSpan

fn clone(&self) -> TextSpan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextSpan

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

Formats the value using the given formatter.

impl Default for TextSpan

fn default() -> TextSpan

Returns the “default value” for a type.

impl Hash for TextSpan

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

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 Ord for TextSpan

fn cmp(&self, other: &TextSpan) -> 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 TextSpan

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

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