Struct Position

struct Position {
    coordinates: (u8, u8),
    facing: Facing,
    score: u32,
    distance: u32,
    visited: Vec<(u8, u8)>,
}

A node in the graph search storing the position and facing, the score and estimated distance to the goal to allow ordering, and a record of the path taken to reach this node.

Fields

coordinates: (u8, u8)

facing: Facing

score: u32

distance: u32

visited: Vec<(u8, u8)>

Implementations

impl Position

pub fn new( coordinates: (u8, u8), facing: Facing, score: u32, distance: u32, visited: Vec<(u8, u8)>, ) -> Self

fn turn_to(&self, facing: Facing, maze: &Maze) -> Self

The updated facing, cost and remaining distance guess after turning to a new facing

fn step(&self, maze: &Maze) -> Option<Self>

The updated coordinates, cost, remaining distance guess, and path travelled afters stepping forward. None if blocked. facing

fn next(&self, maze: &Maze) -> Vec<Position>

From a given position, provide the Position after all possible next moves.

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl Ord for Position

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Position

fn eq(&self, other: &Position) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Position

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
