PositionEncoding

solidity_language_server::utils

Enum PositionEncoding 

Source 
pub enum PositionEncoding {
    Utf8,
    Utf16,
}
Expand description

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§

Source§

impl PositionEncoding

Source

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).

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
