Struct ncpalette 

#[repr(C)]
pub struct ncpalette {
    pub chans: [u32; 256],
}

Palette API. Some terminals only support 256 colors, but allow the full palette to be specified with arbitrary RGB colors. In all cases, it’s more performant to use indexed colors, since it’s much less data to write to the terminal. If you can limit yourself to 256 colors, that’s probably best.

Fields

chans: [u32; 256]

RGB values as regular ol’ channels

Implementations

impl ncpalette

pub fn new<'a>(nc: &mut Nc) -> &'a mut Self

Returns a new NcPalette.

C style function: ncpalette_new().

pub fn free(&mut self)

Frees this NcPalette.

C style function: ncpalette_free().

pub fn use(&self, nc: &mut Nc) -> NcResult<()>

Attempts to configure the terminal with this NcPalette.

C style function: ncpalette_use().

pub fn get(&self, index: impl Into<NcPaletteIndex>) -> NcRgb

Returns the NcRgb value from an NcChannel entry inside this NcPalette.

C style function: ncpalette_get().

pub fn set(&mut self, index: impl Into<NcPaletteIndex>, rgb: impl Into<NcRgb>)

Sets the NcRgb value of the NcChannel entry inside this NcPalette.

C style function: ncpalette_set().

impl ncpalette

pub const SIZE: u32 = 256u32

The supported palette-indexed colors number is up to 8 bits.

Trait Implementations

impl Clone for ncpalette

fn clone(&self) -> ncpalette

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ncpalette

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

Formats the value using the given formatter.

impl Default for ncpalette

fn default() -> Self

Returns the “default value” for a type.

impl Hash for ncpalette

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 Ord for ncpalette

fn cmp(&self, other: &ncpalette) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ncpalette

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

impl PartialOrd for ncpalette

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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