Enum `IntErrorKind`

#[non_exhaustive]
pub enum IntErrorKind

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

Example

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

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 or the converting integer has a value of zero, which would be illegal for non-zero types.

NotAPowerOfTwo

Value is not a power of two.

This variant will be emitted when converting an integer that is not a power of two. This is required in some cases such as constructing an Alignment.
