Enum Blitter 

#[non_exhaustive]
pub enum Blitter {
    Default,
    Ascii,
    Half,
    Quadrant,
    Sextant,
    Braille,
    Pixel,
    _4x1,
    _8x1,
}

Blitter mode to use for rasterizing a Visual.

We never blit full blocks, but instead spaces (more efficient) with the background set to the desired foreground.

Degradation

There is a mechanism of graceful degradation, that works as follows:

Pixel > Sextant > Quadrant > Half > Ascii.

If you don’t want this behaviour you have to call the degrade method of VisualBuilder (or the set_degrade method of Visual) to false.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default

Ascii

Blitter mode using only spaces, compatible with ASCII (1x1).

Half

Blitter mode using halves + Ascii (2x1).

▄▀

Quadrant

Blitter mode using quadrants + Half (2x2).

▗▐ ▖▀▟▌▙

Sextant

Blitter mode using sextants + Quadrant (3x2).

impl Blitter

aliases

pub const _1x1: Blitter = Blitter::Ascii

pub const _2x1: Blitter = Blitter::Half

impl Blitter

methods

pub const fn cell_height(&self) -> Option<u8>

The number of height subdivisions in a cell using the current blitter.

Default & Pixel returns None.

pub const fn cell_width(&self) -> Option<u8>

The number of width subdivisions in a cell using the current blitter.

Default & Pixel returns None.

pub const fn cell_size(&self) -> Option<(u8, u8)>

The inner Cell’s dimensions (width, height) using the current blitter.

Default & Pixel returns None.

Trait Implementations

impl Clone for Blitter

fn clone(&self) -> Blitter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Blitter

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

Formats the value using the given formatter.

impl Default for Blitter

fn default() -> Self

Returns the “default value” for a type.

impl Display for Blitter

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

Formats the value using the given formatter.

impl From<Blitter> for NcBlitter

fn from(blitter: Blitter) -> NcBlitter

Converts to this type from the input type.

impl From<Blitter> for NcBlitter_u32

fn from(blitter: Blitter) -> NcBlitter_u32

Converts to this type from the input type.

impl PartialEq for Blitter

fn eq(&self, other: &Blitter) -> 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.
