Struct TextRange 

pub struct TextRange { /* private fields */ }

A half-open byte range [start, end) into the original source.

This is ronin-core’s own range type so no rowan type leaks across the API boundary (INV-7). Offsets are absolute byte offsets into the accepted UTF-8 source.

Implementations

impl TextRange

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

Construct a range from absolute byte offsets. start <= end is required.

pub fn start(self) -> usize

Inclusive start offset (bytes).

pub fn end(self) -> usize

Exclusive end offset (bytes).

pub fn len(self) -> usize

Byte length of the range.

pub fn is_empty(self) -> bool

true if the range covers zero bytes.

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

true if offset falls within [start, end).
