Struct creusot_contracts::std::num::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 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.

Example

if let Err(e) = i32::from_str_radix("a12", 10) {
    println!("Failed conversion to i32: {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<(), Error>

Formats the value using the given formatter.

impl Display for ParseIntError

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

Formats the value using the given formatter.

impl Error for ParseIntError

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type based access to context intended for error reports.

impl PartialEq 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: &Rhs) -> bool

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