• case_sensitive - A flag indicating whether the search should be case-sensitive.

Examples

use quewuigrep::Config;
use std::env;
 
let args: Vec<String> = vec!["program".into(), "query".into(), "filename.txt".into()];
let config = Config::new(&args).unwrap();
assert_eq!(config.query, "query");
assert_eq!(config.filename, "filename.txt");
assert!(config.case_sensitive);

Fields

query: String

filename: String

case_sensitive: bool

Implementations

impl Config

pub fn new(args: Args) -> Result<Config, &'static str>

Creates a new Config instance from command-line arguments.

Arguments

• args - An iterator over the command-line arguments.

Returns

• Result<Config, &'static str> - Returns a Config instance if successful, or an error message if not.

Examples

use quewuigrep::Config;
use std::env;
 
let args: Vec<String> = vec!["program".into(), "query".into(), "filename.txt".into()];
let config = Config::new(&args).unwrap();
assert_eq!(config.query, "query");
assert_eq!(config.filename, "filename.txt");
assert!(config.case_sensitive);
