Enum IntErrorKind

#[non_exhaustive]
pub enum IntErrorKind {
    Empty,
    InvalidDigit,
    PosOverflow,
    NegOverflow,
    Zero,
}

Enum to store the various types of errors that can cause parsing an integer to fail.

Example

if let Err(e) = i32::from_str_radix("a12", 10) {
    println!("Failed conversion to i32: {:?}", e.kind());
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
