Struct boolean_enums::lstd::num::ParseIntError

pub struct ParseIntError { /* fields omitted */ }

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 the primitive integer types, such as i8::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.

Methods

impl ParseIntError

pub fn kind(&self) -> &IntErrorKind

🔬 This is a nightly-only experimental API. (int_error_matching)

it can be useful to match errors when making error messages for integer parsing

Outputs the detailed cause of parsing an integer failing.

Trait Implementations

impl Error for ParseIntError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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 Display for ParseIntError

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

Formats the value using the given formatter.

impl Eq for ParseIntError

impl PartialEq<ParseIntError> for ParseIntError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for ParseIntError

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

Formats the value using the given formatter.
