Enum ColorLevel 

pub enum ColorLevel {
    None,
    Basic,
    Ansi256,
    TrueColor,
}

The level of color support detected for the terminal.

Variants

None

No color support (monochrome terminals, NO_COLOR env)

Basic

Basic 16-color ANSI support (colors 0-15)

Ansi256

256-color support (colors 0-255)

TrueColor

24-bit truecolor RGB support (16 million colors)

Implementations

impl ColorLevel

pub fn has_color(self) -> bool

Returns true if at least basic color is supported.

pub fn has_256(self) -> bool

Returns true if 256-color mode is supported.

pub fn has_truecolor(self) -> bool

Returns true if 24-bit truecolor is supported.
