Struct FullTextDocument

pub struct FullTextDocument { /* private fields */ }

Implementations

impl FullTextDocument

pub fn new(language_id: String, version: i32, content: String) -> Self

pub fn update( &mut self, changes: &[TextDocumentContentChangeEvent], version: i32, )

pub fn language_id(&self) -> &str

Document’s language id

pub fn version(&self) -> i32

Document’s version

pub fn get_content(&self, range: Option<Range>) -> &str

Get document content

Examples

Basic usage:

use lsp_textdocument::FullTextDocument;
use lsp_types::{Range, Position};

let text_documents = FullTextDocument::new("plain_text".to_string(), 1, "hello rust!".to_string());

// get document all content
let content = text_documents.get_content(None);
assert_eq!(content, "hello rust!");

// get document specify content by range
let (start, end) = (Position::new(0, 1), Position::new(0, 9));
let range = Range::new(start, end);
let sub_content = text_documents.get_content(Some(range));
assert_eq!(sub_content, "ello rus");

pub fn line_count(&self) -> u32

A amount of document content line

pub fn content_len(&self) -> u32

The length of the document content in UTF-8 bytes

pub fn position_at(&self, offset: u32) -> Position

Converts a zero-based byte offset in the UTF8-encoded content to a position

the offset is in bytes, the position is in UTF16 code units. rounds down if the offset is not on a code unit boundary, or is beyond the end of the content.

pub fn offset_at(&self, position: Position) -> u32

Converts a position to a zero-based byte offset, suitable for slicing the UTF-8 encoded content.
