Enum ColorMode 

pub enum ColorMode {
    Auto,
    Always,
    Never,
}

Whether the terminal dump serializers (crate::dump_root, crate::dump_ops, crate::dump_node, crate::dump_function_spans) emit ANSI color escapes.

This is the library-facing color policy. The CLI resolves user intent (an explicit --color flag, the NO_COLOR convention, and stdout tty detection) into one of these variants and threads it into the *_with_color dump entry points.

Variants

Auto

Color only when the underlying stream and environment permit it.

Maps to termcolor::ColorChoice::Auto, which honors NO_COLOR and TERM=dumb. Note that Auto does not itself check whether stdout is a terminal — a caller that wants “no color when piped” must resolve a redirected stream to ColorMode::Never before constructing the writer (the CLI does this via std::io::IsTerminal).

Always

Always emit color escapes, regardless of stream or environment.

Never

Never emit color escapes.

Trait Implementations

impl Clone for ColorMode

fn clone(&self) -> ColorMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColorMode

impl Debug for ColorMode

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

Formats the value using the given formatter.

impl Default for ColorMode

fn default() -> ColorMode

Returns the “default value” for a type.

impl Eq for ColorMode

impl PartialEq for ColorMode

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