Trait ParseCache 

pub trait ParseCache<L: Language>: LexerCache<L> {
    // Required methods
    fn arena(&self) -> &SyntaxArena;
    fn old_tree(&self) -> Option<&GreenNode<'_, L>>;
    fn lex_output(&self) -> Option<&LexOutput<L>>;
    fn prepare_generation(&mut self);
    fn commit_generation(&self, root: &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<&LexOutput<L>>

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.
