Struct int_enum::IntEnumError

pub struct IntEnumError<T: IntEnum> { /* fields omitted */ }

An error when attempting to convert an integer into an enum.

Methods

impl<T: IntEnum> IntEnumError<T>

pub fn value(&self) -> T::Int

Returns the value that could not be converted.

Trait Implementations

impl<T: Clone + IntEnum> Clone for IntEnumError<T> where
    T::Int: Clone, 

fn clone(&self) -> IntEnumError<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Copy + IntEnum> Copy for IntEnumError<T> where
    T::Int: Copy, 

impl<T: IntEnum> Debug for IntEnumError<T>

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

Formats the value using the given formatter.

impl<T: IntEnum> Display for IntEnumError<T>

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

Formats the value using the given formatter.

impl<T: Eq + IntEnum> Eq for IntEnumError<T> where
    T::Int: Eq, 

impl<T: IntEnum> Error for IntEnumError<T>

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

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

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<T: PartialEq + IntEnum> PartialEq<IntEnumError<T>> for IntEnumError<T> where
    T::Int: PartialEq, 

fn eq(&self, other: &IntEnumError<T>) -> bool

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

fn ne(&self, other: &IntEnumError<T>) -> bool

This method tests for !=.
