Struct rustemo::TreeBuilder

pub struct TreeBuilder<'i, I, P, TK>
where
    I: Input + ?Sized,
{ /* private fields */ }

TreeBuilder is a builder that builds a generic concrete parse tree.

Implementations

impl<'i, I, P, TK> TreeBuilder<'i, I, P, TK>

where I: Input + ?Sized,

pub fn new() -> Self

Trait Implementations

impl<'i, I, P, TK> Builder for TreeBuilder<'i, I, P, TK>

where I: Input + ?Sized,

type Output = TreeNode<'i, I, P, TK>

A type produced by this builder. See get_result.

fn get_result(&mut self) -> Self::Output

Returns the product of parsing. Usually the one and only element left on the result stack.

impl<'i, I, P, TK> Default for TreeBuilder<'i, I, P, TK>

where I: Input + ?Sized,

fn default() -> Self

Returns the “default value” for a type.

impl<'i, I, C, S, P, TK> LRBuilder<'i, I, C, S, P, TK> for TreeBuilder<'i, I, P, TK>

where I: Input + ?Sized, C: Context<'i, I, S, TK>, S: State,

fn shift_action(&mut self, context: &mut C, token: Token<'i, I, TK>)

Called when LR shifting is taking place.

fn reduce_action(&mut self, context: &mut C, prod: P, prod_len: usize)

Called when LR reduce is taking place.
