Trait GrTreeExt 

pub trait GrTreeExt {
    // Required methods
    fn get_dup(&mut self, dup_index: &mut Dup) -> usize;
    fn to_str(
        &self,
        start_node: Option<usize>,
        symbol_table: Option<&SymbolTable>,
    ) -> String;
    fn to_str_index(
        &self,
        start_node: Option<usize>,
        symbol_table: Option<&SymbolTable>,
    ) -> String;
}

Adds methods to GrTree.

NOTE: We must create a trait for GrTree since we can’t implement functions for an external type, and a type alias is not considered as a new type.

Required Methods

fn get_dup(&mut self, dup_index: &mut Dup) -> usize

fn to_str( &self, start_node: Option<usize>, symbol_table: Option<&SymbolTable>, ) -> String

fn to_str_index( &self, start_node: Option<usize>, symbol_table: Option<&SymbolTable>, ) -> String
