Struct Path 

pub struct Path<'a, D> {
    pub tokens: SmallVec<[&'a Address; 5]>,
    pub edge_data: SmallVec<[&'a EdgeData<D>; 4]>,
}

A route with a pool chosen for every leg.

Borrows from the graph rather than copying it, so scoring and simulation read a leg’s component id and weight without a lookup.

Fields

tokens: SmallVec<[&'a Address; 5]>

The tokens the route passes through, in order.

edge_data: SmallVec<[&'a EdgeData<D>; 4]>

The pool taken on each leg. One shorter than tokens.

Implementations

impl<'a, D> Path<'a, D>

pub fn new() -> Self

Creates a new empty Path.

pub fn add_hop( &mut self, from: &'a Address, edge_data: &'a EdgeData<D>, to: &'a Address, )

Adds a hop to the path.

Arguments:

• from: The starting token address of the hop.
• edge_data: The edge data for the hop.
• to: The ending token address of the hop.

pub fn len(&self) -> usize

Returns the number of hops in the path.

pub fn is_empty(&self) -> bool

Returns true if the path has no hops.

pub fn edge_iter(&self) -> &[&'a EdgeData<D>]

Returns an iterator over the edges in the path.

pub fn iter( &self, ) -> impl Iterator<Item = (&'a Address, &'a EdgeData<D>, &'a Address)> + '_

Returns an iterator over hops in the path (from_token, edge_data, to_token).

pub fn reversed(self) -> Self

Creates a new reversed Path from the current one.

Trait Implementations

impl<D> Clone for Path<'_, D>

Written out rather than derived so the copy is a memcpy: SmallVec takes that path only through from_slice, which the derived Clone cannot call.

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, D: Default> Default for Path<'a, D>

fn default() -> Path<'a, D>

Returns the “default value” for a type.
