Function finger 

pub fn finger(
    query: &Query,
    timeout: Duration,
    max_response_size: u64,
) -> Result<String, FingerError>

Execute a finger query over TCP, returning the response as a string.

Calls finger_raw and decodes the response with String::from_utf8_lossy. Invalid UTF-8 bytes are replaced with U+FFFD. The response is capped at max_response_size bytes.

Example

use std::time::Duration;
use digit::query::Query;
use digit::protocol::finger;

let q = Query::parse(Some("user@example.com"), false, 79).unwrap();
let response = finger(&q, Duration::from_secs(10), 1_048_576).unwrap();
println!("{}", response);
