Struct Config 

pub struct Config { /* private fields */ }

Configuration for a minigrep run.

Contains the search query, the filename to search, and whether the search is case-sensitive.

Implementations

impl Config

pub fn new(args: &[String]) -> Result<Config, &str>

Create a new Config from CLI-style arguments.

Expects at least three arguments: program name, query, filename. The CASE_INSENSITIVE environment variable toggles case sensitivity: if it is present the search will be case-insensitive.

Returns Err with a short message when args are not sufficient.
