Enum Graphics 

pub enum Graphics {
    Kitty,
    Sixel,
    HalfBlock,
    None,
}

The way a picture can be drawn in this terminal, sharpest first.

Variants

Kitty

The kitty graphics protocol: real pixels, sent once and placed again by number. Kitty, WezTerm, Ghostty and Konsole answer to it.

Sixel

DEC sixel: real pixels, written out whole each time. foot, WezTerm, mlterm, Windows Terminal and a configured xterm answer to it.

HalfBlock

Half blocks: each cell shows two pixels, the upper one as the colour of ▀, the lower one as the cell’s ground. Every terminal with 256 or more colours shows it, over any link.

None

No picture at all: the terminal has 16 colours or draws in ASCII, where a picture cannot be told apart from noise. A picture’s place shows what it is instead.

Implementations

impl Graphics

pub const ALL: [Self; 4]

Every value, sharpest first.

pub fn name(self) -> &'static str

The name the QUVYTA_GRAPHICS environment variable takes for this value: kitty, sixel, halfblock or none.

pub fn can_draw(self) -> bool

Whether a picture is drawn at all: true for everything but Graphics::None.

It is the question the Image widget asks itself before it draws, so an application that would rather show nothing than the image’s “cannot show” state, such as a wallpaper, asks it first and gets the same answer. Read it from Env::graphics in view, or from App::graphics before decoding.

pub fn from_name(name: &str) -> Option<Self>

The value name stands for, as Graphics::name writes it; case and surrounding space do not matter. None for any other name.

Trait Implementations

impl Clone for Graphics

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 Graphics

impl Debug for Graphics

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

Formats the value using the given formatter.

impl Eq for Graphics

impl Hash for Graphics

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Graphics

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

Equality operator ==.

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

Inequality operator !=.
