Expand description
Helps to use coloring only if the output goes to a tty.
Is used in
Logger::adaptive_format_for_stderr
and
Logger::adaptive_format_for_stdout
,
which switch off coloring if the output is not going to a tty but is piped into another
program, because then color control byte sequences are usually not expected.
Variants§
Default
Chooses between default_format
and colored_default_format
.
Detailed
Chooses between detailed_format
and colored_detailed_format
.
Opt
Chooses between opt_format
and colored_opt_format
.
WithThread
Chooses between with_thread
and colored_with_thread
.
Custom(fn(&mut dyn Write, &mut DeferredNow, &Record<'_>) -> Result<(), Error>, fn(&mut dyn Write, &mut DeferredNow, &Record<'_>) -> Result<(), Error>)
Chooses between the first format function (which is supposed to be uncolored) and the second (which is supposed to be colored).
Allows providing own format functions, with freely choosable coloring technique, and making use of the tty detection.
