Struct failure::Compat

pub struct Compat<E> { /* fields omitted */ }

A compatibility wrapper around an error type from this crate.

Compat implements std::error::Error, allowing the types from this crate to be passed to interfaces that expect a type of that trait.

Implementations

impl<E> Compat<E>

pub fn into_inner(self) -> E

Unwraps this into the inner error.

pub fn get_ref(&self) -> &E

Gets a reference to the inner error.

Trait Implementations

impl<E: Clone> Clone for Compat<E>

fn clone(&self) -> Compat<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Copy> Copy for Compat<E>

impl<E: Debug> Debug for Compat<E>

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

Formats the value using the given formatter.

impl<E: Default> Default for Compat<E>

fn default() -> Compat<E>

Returns the "default value" for a type.

impl<E: Display> Display for Compat<E>

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

Formats the value using the given formatter.

impl<E: Eq> Eq for Compat<E>

impl<E: Display + Debug> Error for Compat<E>

fn description(&self) -> &'static str

👎 Deprecated since 1.42.0:

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<E: Hash> Hash for Compat<E>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl<E: PartialEq> PartialEq<Compat<E>> for Compat<E>

fn eq(&self, other: &Compat<E>) -> bool

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

fn ne(&self, other: &Compat<E>) -> bool

This method tests for !=.
