) -> FmtResult;
}
Expand description
An utility alternative core::fmt::Debug
trait which can used for colored
context formatting.
This trait is not intended to be used directly. It is used for coloring
functions and arguments data returned by macros like
build_unwind_context_data
or unwind_context
instead.
§Examples
use unwind_context::{are_colors_enabled, unwind_context, DebugAnsiColored};
fn fmt_example(writer: core::fmt::Write, value: impl Debug + DebugAnsiColored) {
if are_colors_enabled() {
let _ = writeln!(
"{:?}",
AnsiColored::new(value, &unwind_context::DEFAULT_DEFAULT_COLOR_SCHEME)
);
} else {
let _ = writeln!("{value:?}");
}
}
Required Methods§
sourcefn fmt_colored(
&self,
f: &mut Formatter<'_>,
color_scheme: &'static AnsiColorScheme
) -> FmtResult
fn fmt_colored( &self, f: &mut Formatter<'_>, color_scheme: &'static AnsiColorScheme ) -> FmtResult
Formats the value using with colorization and a given
AnsiColorScheme
.
§Errors
This function will return an error if the value formatting fails.
