Enum ColorProfile 

pub enum ColorProfile {
    Mono,
    Ansi16,
    Ansi256,
    TrueColor,
}

Terminal color profile used for downgrade decisions.

Variants

Mono

No color output.

Ansi16

Standard 16 ANSI colors.

Ansi256

Extended 256-color palette.

TrueColor

Full 24-bit RGB color.

Implementations

impl ColorProfile

pub fn detect() -> Self

Auto-detect the best available color profile from environment variables.

Detection priority:

1. NO_COLOR set → Mono
2. COLORTERM=truecolor or COLORTERM=24bit → TrueColor
3. TERM contains “256” → Ansi256
4. Otherwise → Ansi16

Example

use ftui_style::ColorProfile;

let profile = ColorProfile::detect();
if profile.supports_true_color() {
    println!("Full 24-bit color available!");
}

pub fn detect_from_env( no_color: Option<&str>, colorterm: Option<&str>, term: Option<&str>, ) -> Self

Detect color profile from provided environment values (for testing).

Pass Some("") for empty env vars or None for unset.

pub const fn from_flags( true_color: bool, colors_256: bool, no_color: bool, ) -> Self

Choose the best available profile from detection flags.

no_color should reflect explicit user intent (e.g. NO_COLOR).

pub const fn supports_true_color(self) -> bool

Check if this profile supports 24-bit true color.

pub const fn supports_256_colors(self) -> bool

Check if this profile supports 256 colors or more.

pub const fn supports_color(self) -> bool

Check if this profile supports any color (not monochrome).

Trait Implementations

impl Clone for ColorProfile

fn clone(&self) -> ColorProfile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorProfile

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

Formats the value using the given formatter.

impl Hash for ColorProfile

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 ColorProfile

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