    L: Language,
{
    // Required methods
    fn arena(&self) -> &SyntaxArena;
    fn old_tree(&self) -> Option<&GreenNode<'_, L>>;

}

Trait for providing resources and caching for a parsing session.

Required Methods

fn arena(&self) -> &SyntaxArena

Returns the arena for allocating nodes in the current generation.

fn old_tree(&self) -> Option<&GreenNode<'_, L>>

Returns the root of the previous tree for incremental parsing.

fn lex_output( &self, ) -> Option<&OakDiagnostics<Arc<[Token<<L as Language>::TokenType>]>>>

Returns the output of the lexing phase.

fn prepare_generation(&mut self)

Prepares for a new parsing generation (e.g. by swapping arenas).

fn commit_generation(&self, root: &GreenNode<'_, L>)

Commits the result of a parsing generation.
