Enum PositionEncoding 

pub enum PositionEncoding {
    Utf8,
    Utf16,
}

How the LSP client counts column offsets within a line.

Set once during initialize() via set_encoding and read implicitly by byte_offset_to_position and position_to_byte_offset. All other modules are encoding-agnostic — they never need to know or pass this value.

Variants

Utf8

Column = number of bytes from the start of the line (UTF-8 code units).

Utf16

Column = number of UTF-16 code units from the start of the line. This is the mandatory default per the LSP specification.

Implementations

impl PositionEncoding

pub const DEFAULT: Self = PositionEncoding::Utf16

The mandatory LSP fallback encoding.

pub fn negotiate(client_encodings: Option<&[PositionEncodingKind]>) -> Self

Pick the best encoding from the set the client advertises.

Preference: UTF-8 if supported, otherwise UTF-16 (the mandatory fallback).

pub fn to_encoding_kind(self) -> PositionEncodingKind

Convert to the LSP wire type.

Trait Implementations

impl Clone for PositionEncoding

fn clone(&self) -> PositionEncoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PositionEncoding

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

Formats the value using the given formatter.

impl PartialEq for PositionEncoding

fn eq(&self, other: &PositionEncoding) -> 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.
