Enum ColorChoice 

pub enum ColorChoice {
    Always,
    Never,
}

Whether haz run’s presenter renders ANSI colour sequences.

The decision is binary: colour-render bytes go out, or they don’t. The mid-state (“auto”) is resolved at construction time by Self::detect, which probes the live process environment and the live stdout / stderr handles. Once a ColorChoice is built it is a fixed runtime value the presenter consults on every byte.

Variants

Always

Colour escape sequences are emitted on every styled span.

Never

No escape sequence reaches either sink; the presenter emits plain text only.

Implementations

impl ColorChoice

pub fn detect() -> Self

Probe the live process for the colour decision: both streams MUST be terminals AND NO_COLOR MUST be unset or empty for colours to be on.

pub fn is_enabled(self) -> bool

Convenience predicate: true iff Self::Always.
