pub struct ColorArg(pub ColorChoice);
Expand description

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

use codespan_reporting::term::termcolor::StandardStream;
use codespan_reporting::term::ColorArg;
use structopt::StructOpt;

#[derive(Debug, StructOpt)]
#[structopt(name = "groovey-app")]
pub struct Opts {
    /// Configure coloring of output
    #[structopt(
        long = "color",
        default_value = "auto",
        possible_values = ColorArg::VARIANTS,
        case_insensitive = true,
    )]
    pub color: ColorArg,
}

let opts = Opts::from_args();
let writer = StandardStream::stderr(opts.color.into());

Implementations§

Allowed values the argument.

This is useful for generating documentation via clap or structopt’s possible_values configuration.

Converts this type into the (usually inferred) input type.
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
