Struct Look 

pub struct Look {
    pub palette: [Rgb; 256],
    pub fonts: [u8; 4],
    pub bright_font: bool,
    pub bright_plain: bool,
    pub blink_font: bool,
    pub blink_steady: bool,
    pub loaded: Vec<LoadedFont>,
}

What a BBS can change about how cells are drawn, beyond their own attributes: CTerm’s palette (OSC 4) and font slots (CSI n;m SP D).

Fields

palette: [Rgb; 256]

In xterm order: the 16 ANSI colors (black, red, green, …), the 6x6x6 cube and the grays.

fonts: [u8; 4]

CTerm font IDs for the normal, bright, blink and bright-blink slots.

bright_font: bool

CSI ?31h: bright text is drawn in font slot 1.

bright_plain: bool

CSI ?32h: bold does not brighten the color.

blink_font: bool

CSI ?34h: blinking text is drawn in font slot 2.

blink_steady: bool

CSI ?35h: blink does not make text blink.

loaded: Vec<LoadedFont>

Fonts the BBS has loaded (CTerm’s loadable fonts), by slot.

Implementations

impl Look

pub fn standard() -> &'static Look

The VGA palette and font, with no CTerm modes set.

pub fn load_font(&mut self, slot: u8, data: &[u8]) -> bool

Load a font into a slot: 4096 bytes is 8x16, 3584 8x14, 2048 8x8. False if the slot is a built-in one or the size is none of those.

pub fn loaded_font(&self, slot: u8) -> Option<LoadedFont>

A loaded font, by its slot (the ID CSI n ; slot SP D selects).

pub fn rgb(&self, c: Color) -> Rgb

pub fn font_for(&self, cell: &Cell) -> u8

The CTerm font a cell is drawn in.

Trait Implementations

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for Look

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

Formats the value using the given formatter.

impl Default for Look

fn default() -> Look

Returns the “default value” for a type.

impl Eq for Look

impl PartialEq for Look

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

Equality operator ==.

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

Inequality operator !=.
