Struct mdns::errors::Error

pub struct Error {
    pub kind: ErrorKind,
    pub state: State,
}

The Error type

This has a simple structure to support pattern matching during error handling. The second field is internal state that is mostly irrelevant for error handling purposes.

Fields

kind: ErrorKind

The kind of the error.

state: State

Contains the error chain and the backtrace.

Methods

impl Error

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

Returns the backtrace associated with this error.

impl Error

fn from_kind(kind: ErrorKind) -> Error

Constructs an error from a kind.

fn kind(&self) -> &ErrorKind

Returns the kind of the error.

fn iter(&self) -> ErrorChainIter

Iterates over the error chain.

Methods from Deref<Target = ErrorKind>

fn description(&self) -> &str

A string describing the error kind.

Trait Implementations

impl Debug for Error

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl ChainedError for Error

type ErrorKind = ErrorKind

Associated kind type.

fn new(kind: ErrorKind, state: State) -> Error

Creates an error from it's parts.

fn extract_backtrace(
    e: &Error + Send + 'static
) -> Option<Option<Arc<Backtrace>>>

Returns the first known backtrace, either from it's State or from one of the errors from foreign_links.

impl Error for Error

fn description(&self) -> &str

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