Enum std::num::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)

Value being parsed is empty.

This variant will be constructed when parsing an empty string.

Contains an invalid digit in its context.

Among other causes, this variant will be constructed when parsing a string that contains a non-ASCII char.

This variant is also constructed when a + or - is misplaced within a string either on its own or in the middle of a number.

Integer is too large to store in target integer type.

Integer is too small to store in target integer type.

Value was Zero

This variant will be emitted when the parsing string has a value of zero, which would be illegal for non-zero types.
