Struct TextRange 

pub struct TextRange { /* private fields */ }

A half-open byte range into the source text.

Ranges are byte offsets, not char offsets. GDScript source is UTF-8 and the lexer only ever splits on ASCII boundaries, so every range produced here is guaranteed to land on a char boundary.

Implementations

impl TextRange

pub const fn new(start: u32, end: u32) -> Self

pub const fn empty(offset: u32) -> Self

A zero-width range at offset, used for synthetic tokens such as Indent, Dedent and Eof.

pub const fn start(self) -> u32

pub const fn end(self) -> u32

pub const fn len(self) -> u32

pub const fn is_empty(self) -> bool

pub fn cover(self, other: Self) -> Self

The smallest range covering both self and other.

pub fn slice(self, text: &str) -> &str

Slice text with this range.
