Enum ColorSupport 

#[non_exhaustive]
pub enum ColorSupport {
    Truecolor,
    Indexed256,
    Ansi16,
    None,
}

How aggressively TerminalRenderer quantizes Color before emitting an SGR sequence.

See the crate-level “RGB color fallback on 256-color terminals” doc section for the full contract, and TerminalRenderer::with_color_support/TerminalRenderer::set_color_support to configure it.

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.

Truecolor

No quantization: Color::Rgb tiles are written out verbatim as a 24-bit truecolor SGR sequence. The default, matching this renderer’s historical behavior.

Indexed256

Color::Rgb tiles are quantized to the nearest of the 256 indexed-color palette entries via Color::to_indexed before being written.

Ansi16

Color::Rgb tiles are quantized to the nearest of the 16 standard ANSI colors via Color::to_ansi before being written.

None

Every Color is forced to Color::Default: no SGR color codes are emitted at all.

Trait Implementations

impl Clone for ColorSupport

fn clone(&self) -> ColorSupport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorSupport

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

Formats the value using the given formatter.

impl Default for ColorSupport

fn default() -> ColorSupport

Returns the “default value” for a type.

impl Hash for ColorSupport

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 ColorSupport

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