Enum ColorChoice 

#[non_exhaustive]
pub enum ColorChoice {
    Auto,
    Always,
    Never,
}

When rendered failures should use ANSI color.

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.

Auto

Color when the output looks like a terminal and NO_COLOR is unset. This is the default.

Always

Always emit color, regardless of terminal detection or NO_COLOR.

Never

Never emit color.

Trait Implementations

impl Clone for ColorChoice

fn clone(&self) -> ColorChoice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorChoice

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

Formats the value using the given formatter.

impl PartialEq for ColorChoice

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