Struct TextRange 

pub struct TextRange { /* private fields */ }

Source positions, spans, and text range utilities. A half-open byte range in source text, analogous to ruff’s TextRange.

Implementations

impl TextRange

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

Create a new range from start (inclusive) to end (exclusive).

pub const fn start(self) -> TextSize

Start offset (inclusive).

pub const fn end(self) -> TextSize

End offset (exclusive).

pub const fn len(self) -> TextSize

Length in bytes.

pub const fn is_empty(self) -> bool

Whether the range is empty.

pub fn slice<'a>(&self, source: &'a str) -> &'a str

Slice the source text covered by this range.

pub fn offset_by(self, base: TextSize) -> Self

Shift the range by adding a base offset to both start and end.

Trait Implementations

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

Formats the value using the given formatter.

impl Default for TextRange

fn default() -> TextRange

Returns the “default value” for a type.

impl Hash for TextRange

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 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.
