pub fn prompt<T, S>(msg: S) -> Result<T, ReadlineError> where
T: Promptable,
S: AsRef<str>, Expand description
Prompt until input can be parsed as T.
Empty string input causes a re-prompt (including for String)
Examples
use promptly::prompt;
// Prompt until a non-empty string is provided
let name: String = prompt("Enter your name")?;
// Prompt for other `FromStr` types
let age: u32 = prompt("Enter your age")?;
Errors
Returns a ReadlineError if readline fails.
Input that can’t be coerced into the specified type results in re-prompting.
