Struct quake3_qvm::errors::Error

pub struct Error(_, _);

The Error type.

This struct is made of three things:

• an ErrorKind which is used to determine the type of the error.
• a backtrace, generated when the error is created.
• an error chain, used for the implementation of Error::cause().

Implementations

impl Error

pub fn from_kind(kind: ErrorKind) -> Error

Constructs an error from 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.

Trait Implementations

impl ChainedError for Error

type ErrorKind = ErrorKind

Associated kind type.

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

fn from_kind(kind: Self::ErrorKind) -> Self

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

fn kind(&self) -> &Self::ErrorKind

Returns the kind of the error.

fn iter(&self) -> ErrorChainIter

Iterates over the error chain.

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

Returns the backtrace associated with this error.

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

impl Debug for Error

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

Formats the value using the given formatter.

impl Deref for Error

type Target = ErrorKind

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
