Struct rsclp::CommandLineParserError

pub struct CommandLineParserError { /* private fields */ }

Command line option error representation. This struct is returned by all command line parser methods in case of error you can print its representation simply using {} placeholder in the rust macros

Examples

use rsclp::CommandLineParser;
 
fn main() {
    let mut clp = CommandLineParser::new(None);
    let config_option = clp.add_string_option('c', "config", true, "file path", "configuration file path").unwrap();
    match clp.parse_args(std::env::args()) {
        Ok(()) => {
        let config_file: String = clp.get_value(&config_option).unwrap();
        println!("config_file: {}", config_file);
        },
        Err(parse_error) => {
            eprintln!("{}", parse_error);
            clp.show_help();
        }
    }     
}

Trait Implementations

impl Debug for CommandLineParserError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CommandLineParserError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CommandLineParserError

fn eq(&self, other: &CommandLineParserError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
