Struct DocumentStore 

pub struct DocumentStore { /* private fields */ }

Versioned concurrent document store — replaces RwLock<HashMap<Url, String>> in every LSP backend.

Clone is O(1): all clones share the same inner map via Arc.

Implementations

impl DocumentStore

pub fn new() -> Self

Creates an empty DocumentStore.

pub fn open(&self, uri: Url, content: String, version: i32)

Registers an opened document with its initial content and version.

pub fn update( &self, uri: &Url, changes: Vec<TextDocumentContentChangeEvent>, version: i32, )

Apply a batch of content-change events, then stamp the new version.

pub fn close(&self, uri: &Url)

Removes a document from the store (called on textDocument/didClose).

pub fn get_content(&self, uri: &Url) -> Option<String>

Returns a clone of the document’s current content, or None if not open.

pub fn version(&self, uri: &Url) -> Option<i32>

Returns the current version counter for the document.

pub fn with<F, T>(&self, uri: &Url, f: F) -> Option<T>

where F: FnOnce(&VersionedDocument) -> T,

Applies f to the document without cloning the content string.

pub fn is_open(&self, uri: &Url) -> bool

Returns true if the URI is currently open in the store.

pub fn content_hash(&self, uri: &Url) -> Option<u64>

Returns a FNV-1a hash of the document content, or None if not open.

Callers can use this to skip re-analysis when content hasn’t changed, without cloning the full String.

pub fn activation_count(&self, uri: &Url) -> u64

Returns the number of times this document has been updated since open.

Used to scale debounce delay: high-activation documents (many edits) benefit from a longer quiet window before re-analysis fires.
