[−][src]Struct language_reporting::ColorArg
A command line argument that configures the coloring of the output
This can be used with command line argument parsers like clap
or structopt
.
Example
extern crate language_reporting; #[macro_use] extern crate structopt; use structopt::StructOpt; use termcolor::StandardStream; use language_reporting::ColorArg; #[derive(Debug, StructOpt)] #[structopt(name = "groovey-app")] pub struct Opts { /// Configure coloring of output #[structopt( long = "color", parse(try_from_str), default_value = "auto", raw(possible_values = "ColorArg::VARIANTS", case_insensitive = "true") )] pub color: ColorArg, } fn main() { let opts = Opts::from_args(); let writer = StandardStream::stderr(opts.color.into()); }
Methods
impl ColorArg
[src]

[src]
Allowed values the argument
This is useful for generating documentation via clap
or structopt
's
possible_values
configuration.
