Trait antlr_rust::rule_context::CustomRuleContext

pub trait CustomRuleContext<'input> {
    type TF: TokenFactory<'input> + 'input;
    type Ctx: ParserNodeType<'input, TF = Self::TF>;

    fn get_rule_index(&self) -> usize;

    fn get_alt_number(&self) -> isize { ... }
    fn set_alt_number(&self, _alt_number: isize) { ... }
    fn get_node_text(&self, rule_names: &[&str]) -> String { ... }
}

Implemented by generated parser for context extension for particular rule

Required Associated Types

type TF: TokenFactory<'input> + 'input

type Ctx: ParserNodeType<'input, TF = Self::TF>

Type that describes type of context nodes, stored in this context

Required Methods

fn get_rule_index(&self) -> usize

Rule index that corresponds to this context type

Provided Methods

fn get_alt_number(&self) -> isize

fn set_alt_number(&self, _alt_number: isize)

fn get_node_text(&self, rule_names: &[&str]) -> String

Returns text representation of current node type, rule name for context nodes and token text for terminal nodes
