Struct Origin 

pub struct Origin<F, T> {
    pub trees: Vec<GrTree>,
    pub map: HashMap<F, (VarId, usize)>,
    /* private fields */
}

Fields

trees: Vec<GrTree>

map: HashMap<F, (VarId, usize)>

Implementations

impl<F, T> Origin<F, T>

pub fn new() -> Self

Creates a blank Origin object.

pub fn with_capacity(size: usize) -> Self

Creates a blank Origin object with a tree capacity of size. Use this method when you can’t give the data in a form that suits the other constructors but when you know the number of variables.

pub fn from_data(trees: Vec<GrTree>, map: HashMap<F, (VarId, usize)>) -> Self

Creates an Origin object with the given trees and mapping.

pub fn from_trees_mut(trees: &mut Vec<GrTree>) -> Self

Creates an Origin object with the given trees as mutable reference. It will take the content from trees to create the object. After that, trees is empty.

Use this method to create an Origin object from another generic form of the same type; typically when creating an Origin<(VarId, AltId), FromPRS> from an Origin<(VarId, usize), FromRTS> if you can’t move the original.

pub fn set_tree(&mut self, var: VarId, tree: GrTree)

Sets the original tree of nonterminal var.

pub fn get_tree(&self, var: VarId) -> Option<&GrTree>

Gets the original GrTree of nonterminal var, if it exists.

impl<F: Eq + Hash, T> Origin<F, T>

pub fn add(&mut self, new: F, origin: (VarId, usize))

Adds a connection between a new node and its origin in the original GrTree.

new is made up of a nonterminal index and its tree index.

pub fn get(&self, new: F) -> Option<(&GrTree, usize)>

Gets the original GrTree and node index, if they exist, from a new node.

new is made up of a nonterminal index and its tree index.

Trait Implementations

impl<F: Clone, T: Clone> Clone for Origin<F, T>

fn clone(&self) -> Origin<F, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F: Debug, T: Debug> Debug for Origin<F, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
