Struct LuaCtx 

pub struct LuaCtx(pub Value);

A context value from Lua: any Value, compared by deep equality.

Deep equality is what lets the incremental tree reuse regions across edits: two contexts match only if they are structurally identical (tables recursively; 1 and 1.0 compare equal; functions and other opaque values never compare equal — contexts should be data).

Trait Implementations

impl Clone for LuaCtx

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LuaCtx

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

Formats the value using the given formatter.

impl Eq for LuaCtx

impl Language<LuaCtx> for LuaLanguage

fn supports_symbols(&self) -> bool

Runtime hook for symbol support; defaults to SUPPORTS_SYMBOLS.

fn engine(&self) -> &Engine<LuaCtx>

The pass schedule run over every document.

fn root_ctx(&self) -> LuaCtx

Context for a freshly opened document’s root region.

fn diagnostic( &self, doc: &Document<LuaCtx>, node: FailedNode<'_, LuaCtx>, ) -> Option<Diagnostic>

Renders the diagnostic for a failing region, or None to stay silent (e.g. for contexts whose failure is expected).

fn symbols(&self, doc: &Document<LuaCtx>) -> Vec<DocumentSymbol>

The document symbols for the outline view. Only consulted when supports_symbols is true.

const SUPPORTS_SYMBOLS: bool = false

Whether to advertise and answer textDocument/documentSymbol. Defaults to false; flip to true and override symbols.

fn encoding(&self) -> PositionEncoding

The position encoding to negotiate with the client. Defaults to UTF-16, the LSP default and what most clients use.

fn extra_diagnostics(&self, doc: &Document<C>) -> Vec<Diagnostic>

Diagnostics that do not come from parse failures — lint-rule violations, style warnings, anything computed from the settled document rather than a failing tree node. Merged into the same publishDiagnostics notification, after the parse diagnostics.

fn supports_hover(&self) -> bool

Runtime hook for hover support; defaults to false.

fn supports_definition(&self) -> bool

Runtime hook for go-to-definition support; defaults to false.

fn supports_completion(&self) -> bool

Runtime hook for completion support; defaults to false.

fn supports_code_actions(&self) -> bool

Runtime hook for code-action support (the editor’s quickfix lightbulb); defaults to false.

fn code_action(&self, doc: &Document<C>, range: Range) -> Vec<CodeAction>

Code actions for the given range — typically quickfixes for the diagnostics published there. The skeleton dispatches textDocument/codeAction when supports_code_actions is true.

fn hover(&self, doc: &Document<C>, offset: usize) -> Option<Hover>

Hover contents for the byte offset in doc, or None.

fn definition(&self, doc: &Document<C>, offset: usize) -> Option<Vec<Location>>

Definition locations for the byte offset in doc, or None.

fn completion( &self, doc: &Document<C>, offset: usize, ) -> Option<CompletionResponse>

Completions for the byte offset in doc, or None.

impl PartialEq for LuaCtx

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
