Enum AdaptiveFormat 

pub enum AdaptiveFormat {
    Default,
    Detailed,
    Opt,
    WithThread,
    Custom(fn(&mut dyn Write, &mut DeferredNow, &Record<'_>) -> Result<(), Error>, fn(&mut dyn Write, &mut DeferredNow, &Record<'_>) -> Result<(), Error>),
}

Can be used in Logger::adaptive_format_for_stderr and Logger::adaptive_format_for_stdout to use coloring only if the output goes to a tty.

This is helpful if the output is sometimes piped into other programs, which usually do not expect color control byte sequences.

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.
