Struct xml_rpc::error::Error

[+] Show declaration

pub struct Error(pub ErrorKind, _);

[−] Expand description

The Error type.

This tuple struct is made of two elements:

• an ErrorKind which is used to determine the type of the error.
• An internal State, not meant for direct use outside of error_chain internals, containing:
  • a backtrace, generated when the error is created.
  • an error chain, used for the implementation of Error::cause().

Methods

impl Error[−]

pub fn from_kind(kind: ErrorKind) -> Error[−]

Constructs an error from a kind, and generates a backtrace.

pub fn with_chain<E, K>(error: E, kind: K) -> Error where
    E: Error + Send + 'static,
    K: Into<ErrorKind>, [−]

Constructs a chained error from another error and a kind, and generates a backtrace.

pub fn kind(&self) -> &ErrorKind[−]

Returns the kind of the error.

pub fn iter(&self) -> ErrorChainIter[−]

Iterates over the error chain.

pub fn backtrace(&self) -> Option<&Backtrace>[−]

Returns the backtrace associated with this error.

Methods from Deref<Target = ErrorKind>

pub fn description(&self) -> &str[−]

A string describing the error kind.

impl Error for Error[+]

[+] Show hidden undocumented items

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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.
