# Enum std::num::IntErrorKind

    #[non_exhaustive]
    pub enum IntErrorKind {
        Empty,
        InvalidDigit,

        NegOverflow,

Expand description

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)

This enum is marked as 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.
`Empty`

Value being parsed is empty.

This variant will be constructed when parsing an empty string.

`InvalidDigit`

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.

`PosOverflow`

Integer is too large to store in target integer type.

`NegOverflow`

Integer is too small to store in target integer type.

`Zero`

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.
