Struct ascii_renderer::char_buffer::CharBuffer

pub struct CharBuffer {
    pub data: Vec<Vec<char>>,
    pub dimensions: (usize, usize),
}

The buffer used by the runner and mutated by the logic struct. Just a wrapper around a 2D char vector.

Example

let mut buf = CharBuffer::new(3, 3);
buf.set_char(0, 0, 'n').unwrap();
buf.set_char(2, 1, 'x').unwrap();
buf.set_char(2, 2, 'z').unwrap();
assert_eq!(&buf.to_string(), "n     \n    x \n    z \n");

Fields

data: Vec<Vec<char>>

dimensions: (usize, usize)

Implementations

impl CharBuffer

pub fn new(width: usize, height: usize) -> Self

pub fn get_char(&self, x: usize, y: usize) -> Option<char>

pub fn set_char(
    &mut self,
    x: usize,
    y: usize,
    value: char
) -> Result<(), CharBufferError>

pub fn fill(&mut self, char: char)

Filles the char buffer with the given char

impl CharBuffer

pub fn draw_line(&mut self, line: Line)

Draws an individual line to the buffer

pub fn draw_lines(&mut self, lines: Vec<Line>)

Draws lines to the buffer. The first lines in the vector will be drawn first.

Example

let mut buf = CharBuffer::new(10, 10);
let lines = vec![
    Line {
        char: '+',
        points: (vec2!(2.0, 2.0), vec2!(8.0, 8.0)),
    },
    Line {
        char: '=',
        points: (vec2!(2.0, 8.0), vec2!(8.0, 2.0)),
    },
];
buf.draw_lines(lines);
println!("{buf}");

Trait Implementations

impl Clone for CharBuffer

fn clone(&self) -> CharBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CharBuffer

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

Formats the value using the given formatter.

impl Display for CharBuffer

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

Formats the value using the given formatter.

impl PartialEq<CharBuffer> for CharBuffer

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<CharBuffer> for CharBuffer

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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