Struct ParseIntError

#[non_exhaustive]
pub struct ParseIntError { /* private fields */ }

Error with rich context returned when a string can’t be parsed as an integer.

This is an extension of core::num::ParseIntError, which carries the input that failed to parse as well as type information. As a result it provides very informative error messages that make it easier to understand the problem and correct mistakes.

Note that this is larger than the type from core so if it’s passed through a deep call stack in a performance-critical application you may want to box it or throw away the context by converting to core type.

Implementations

impl ParseIntError

pub fn input(&self) -> &str

Returns the input that was attempted to be parsed.

Trait Implementations

impl AsRef<ParseIntError> for ParseIntError

fn as_ref(&self) -> &ParseIntError

Converts this type into a shared reference of the (usually inferred) input type.

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

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

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 From<ParseIntError> for FromStrError

fn from(e: ParseIntError) -> FromStrError

Converts to this type from the input type.

impl From<ParseIntError> for ParseIntError

fn from(value: ParseIntError) -> ParseIntError

Converts to this type from the input type.

impl From<ParseIntError> for PrefixedHexError

fn from(e: ParseIntError) -> PrefixedHexError

Converts to this type from the input type.

impl From<ParseIntError> for UnprefixedHexError

fn from(e: ParseIntError) -> UnprefixedHexError

Converts to this type from the input type.

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.
