Enum termcolor::ColorChoice
source · pub enum ColorChoice {
Always,
AlwaysAnsi,
Auto,
Never,
}
Expand description
ColorChoice represents the color preferences of an end user.
The Default
implementation for this type will select Auto
, which tries
to do the right thing based on the current environment.
The FromStr
implementation for this type converts a lowercase kebab-case
string of the variant name to the corresponding variant. Any other string
results in an error.
Variants§
Always
Try very hard to emit colors. This includes emitting ANSI colors on Windows if the console API is unavailable.
AlwaysAnsi
AlwaysAnsi is like Always, except it never tries to use anything other than emitting ANSI color codes.
Auto
Try to use colors, but don’t force the issue. If the console isn’t
available on Windows, or if TERM=dumb, or if NO_COLOR
is defined, for
example, then don’t use colors.
Never
Never emit colors.
