Struct Grid

pub struct Grid { /* private fields */ }

This struct contains the grid of a life cellular automaton.

This grid is stored as a Vec<bool>. When it is toroidal, its size is constant. When it is not, it is resized when computing the next generation according to the size of the contained pattern.

The origin of the pattern is also stored in Grid: the coordinates of its north west corner is stored as a (usize, usize).

It also contains the cellular automaton’s rules stored as two Vec<u8>s. These are the survival and birth conditions into survival and birth respectivly.

Implementations

impl Grid

pub fn guess_pattern_origin(&self) -> (usize, usize)

Returns the coordinates of the cell at the upper left corner of the current Grid.

pub fn guess_pattern_size(&self) -> (usize, usize)

Returns the size of the current Grid’s pattern.

pub fn compute_pattern_boundaries( &self, ) -> (Option<usize>, Option<usize>, Option<usize>, Option<usize>)

impl Grid

pub fn from_file(path: &str) -> Result<Grid, FileParsingErrorKind>

Returns a new Grid encoded within a file located at path.

Errors

If there is an IO error or the file isn’t a valid life file, an error of the type FileParsingErrorKind will be returned.

pub fn save_life_grid(&self, path: &str) -> Result<(), Error>

Writes the Grid into a file located at path.

Errors

If there is an IO error, an error of the type io::Error will be returned.

impl Grid

pub fn randomize(&mut self)

Randomizes the current Grid by setting a random state to each cell.

pub fn next_gen(&mut self)

Computes the next generation of the current Grid and updates it.

pub fn recenter_pattern(&mut self, border_width: usize)

impl Grid

pub fn render( &self, x_pos: usize, y_pos: usize, view_width: usize, view_height: usize, img_width: usize, img_height: usize, ) -> Vec<u8>

impl Grid

pub fn new( frmt: &String, trdl: bool, srvl: &Vec<u32>, brth: &Vec<u32>, width: usize, height: usize, ) -> Grid

Returns a new Grid:

• containing the file format frmt
• toroidal if trdl is true, resizable otherwise
• containing the rules given by srvl and brth
• whose grid’s size is determined by width and height

pub fn new_random( frmt: &String, trdl: bool, srvl: &Vec<u32>, brth: &Vec<u32>, width: usize, height: usize, ) -> Grid

Returns a new Grid and initializes its cells randomly.

pub fn get_format(&self) -> String

Returns the file format used.

pub fn set_format(&mut self, frmt: &String)

Sets a new file format for this Grid.

pub fn is_toroidal(&self) -> bool

Returns true if the grid is toroidal. Otherwise the grid is resizable.

pub fn get_survival(&self) -> Vec<u32>

Returns the survival conditions of the cellular automaton.

pub fn set_survival(&mut self, srvl: &Vec<u32>)

Redefines the survival conditions of the cellular automaton.

pub fn get_birth(&self) -> Vec<u32>

Returns the birth conditions of the cellular automaton.

pub fn set_birth(&mut self, brth: &Vec<u32>)

Redefines the birth conditions of the cellular automaton.

pub fn get_width(&self) -> usize

Returns the width of the grid.

pub fn get_height(&self) -> usize

Returns the height of the grid.

pub fn get_cell_state(&self, x: i64, y: i64) -> u8

Returns the state of the cell at the coordinates (x, y).

If the coordinates are out of bounds and the grid is toroidal, then it returns the state of the cell at the coordinates modulo the size of the grid. Otherwise, if the coordinates are out of bounds but the grid is not toroidal, it returns 0u8.

pub fn set_cell_state( &mut self, x: usize, y: usize, state: u8, ) -> Result<(), GridErrorKind>

Modifies the state of the cell at the coordinates (x, y) with state. Returns Err(GridErrorKind::OutOfBoundCoords) if the coordinates are out of bounds.
