Enum Model 

pub enum Model {
    None,
    Sides,
    Corners,
    Blob,
}

The neighbourhood a transition reads, and the patterns it maps to tiles.

Variants

None

No neighbours: every tile has pattern 0. Inside only; for variants.

Sides

The four sides, N 1, E 2, S 4, W 8: 16 patterns.

Corners

The four corners, NE 1, SE 2, SW 4, NW 8: the 16 patterns of a corner (Wang or marching-squares) set.

Blob

Sides and corners, N 1, NE 2, E 4, SE 8, S 16, SW 32, W 64, NW 128, with each corner counted only where its sides allow: 47 patterns.

Implementations

impl Model

pub const fn as_str(self) -> &'static str

pub fn parse(text: &str) -> Option<Self>

The model a document spells text.

pub fn pattern(self, draw: Draw, shows: [bool; 8]) -> u8

The pattern of a tile whose neighbours, N, NE, E, SE, S, SW, W and NW, show the transition’s terrain where shows is true.

pub fn produces(self, draw: Draw, pattern: u8) -> bool

Whether this model produces pattern when drawing draw: the keys a transition’s tiles may have. An outside transition never draws pattern 0, where no neighbour shows its terrain.

Trait Implementations

impl Clone for Model

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Model

impl Debug for Model

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

Formats the value using the given formatter.

impl Eq for Model

impl Hash for Model

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for Model

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.

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Model

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Model

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
