Enum PositionEncoding

pub enum PositionEncoding {
    Utf16,
    Utf8,
}

What counts as “1 character” for string indexing. We should always prefer UTF-8, but support UTF-16 as long as it is standard. For more background on encodings and LSP, try “The bottom emoji breaks rust-analyzer”, a well-written article on the topic.

Variants

Utf16

“1 character” means “1 UTF-16 code unit”

This is the only required encoding for LSPs to support, but it’s not a natural one (unless you’re working in JS). Prefer UTF-8, and refer to the article linked in the PositionEncoding docs for more background.

Utf8

“1 character” means “1 byte”

Trait Implementations

impl Clone for PositionEncoding

fn clone(&self) -> PositionEncoding

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl Default for PositionEncoding

fn default() -> PositionEncoding

Returns the “default value” for a type.

impl Hash for PositionEncoding

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
