Struct Args

pub struct Args {
    pub query: String,
    pub file_path: String,
    pub ignore_case: bool,
}

Struct that defines required/supported arguments

The struct can be used to parse arguments from an iterator.

Fields

query: String

Pattern used as a substring search.

file_path: String

Path to the file that should be opened and used for searching.

ignore_case: bool

Whether the search should be case-sensitive or not.

Implementations

impl Args

pub fn build(args: impl Iterator<Item = String>) -> Result<Args, &'static str>

Builds arguments from an iterator

Expects argument in the order: 0. executable_name

1. query
2. file_path
3. ignore_case (optional)

Examples

let iter = vec![
    String::from("grep_clone"),
    String::from("Who"),
    String::from("poem.txt"),
].into_iter();
let args = grep_clone::Args::build(iter);
