Enum AdaptiveFormat

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

§

Detailed

§

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.
