Enum PositionEncoding 

pub enum PositionEncoding {
    Utf8,
    Utf16,
}

The unit that LSP [Position::character] offsets count, agreed with the client during initialize.

Variants

Utf8

Offsets count UTF-8 bytes.

Utf16

Offsets count UTF-16 code units. This is the LSP default for clients that do not advertise an encoding.

Implementations

impl PositionEncoding

pub fn negotiate(capabilities: &ClientCapabilities) -> Self

Picks UTF-8 when the client lists it in general.positionEncodings, otherwise UTF-16.

pub fn kind(self) -> PositionEncodingKind

The value to report in ServerCapabilities::position_encoding.

pub fn len_of(self, text: &str) -> u32

The length of text in this encoding’s units.

pub fn char_index(self, rope: &Rope, position: Position) -> usize

Converts position to a char index into rope.

A line past the end of the document resolves to the end of the document. A character past the end of a line, or inside a multi-unit character, resolves to the end of that line or the start of that character.

pub fn position(self, rope: &Rope, char_idx: usize) -> Position

Converts a char index into rope to a [Position], clamping indexes past the end to the end of the document.

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 Copy for PositionEncoding

impl Debug for PositionEncoding

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

Formats the value using the given formatter.

impl Default for PositionEncoding

fn default() -> PositionEncoding

Returns the “default value” for a type.

impl Eq for PositionEncoding

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.
