Struct ParseIntError

pub struct ParseIntError { /* private fields */ }

An error which can be returned when parsing an integer.

This error is used as the error type for the from_str_radix() functions on ranged integer types, such as RangedI8::from_str_radix.

Potential causes

Among other causes, ParseIntError can be thrown because of leading or trailing whitespace in the string e.g., when it is obtained from the standard input. Using the str::trim() method ensures that no whitespace remains before parsing.

Example

if let Err(e) = RangedI32::<0, 10>::from_str_radix("a12", 10) {
    println!("Failed conversion to RangedI32: {e}");
}

Implementations

impl ParseIntError

pub fn kind(&self) -> &IntErrorKind

Outputs the detailed cause of parsing an integer failing.

Trait Implementations

impl Clone for ParseIntError

fn clone(&self) -> ParseIntError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParseIntError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ParseIntError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ParseIntError

fn eq(&self, other: &ParseIntError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
