Struct Utf16OffsetConverter 

pub struct Utf16OffsetConverter { /* private fields */ }

UTF-8 byte offset to UTF-16 code unit offset converter

CodeMirror 6 uses absolute UTF-16 code unit offsets for positions. This converter provides O(1) lookups after O(n) preprocessing.

Implementations

impl Utf16OffsetConverter

pub fn new(input: &str) -> Self

Creates a new converter with O(n) preprocessing

Builds a lookup table mapping each byte position to its corresponding UTF-16 code unit position.

pub fn convert(&self, byte_offset: usize) -> u32

Converts a byte offset to UTF-16 code unit offset in O(1)

pub fn convert_span(&self, span: &Span) -> Utf16Position

Converts a Span to UTF-16 position

pub fn convert_elements(&self, elements: &[Element]) -> Value

Converts SevenMark AST elements to JSON with UTF-16 positions
