Struct Error 

pub struct Error(/* private fields */);

An Objective-C error object.

C++ equivalent: NS::Error

Implementations

impl Error

pub fn error( domain: ErrorDomain, code: Integer, user_info: *mut Dictionary, ) -> Option<Self>

Create an error with the specified domain, code, and user info.

C++ equivalent: static Error* error(ErrorDomain domain, Integer code, class Dictionary* pDictionary)

pub fn alloc() -> Option<Self>

Allocate a new error.

C++ equivalent: static Error* alloc()

pub fn init(&self) -> Option<Self>

Initialize an allocated error.

C++ equivalent: Error* init()

pub fn init_with_domain( &self, domain: ErrorDomain, code: Integer, user_info: *mut Dictionary, ) -> Option<Self>

Initialize with domain, code, and user info.

C++ equivalent: Error* init(ErrorDomain domain, Integer code, class Dictionary* pDictionary)

pub fn code(&self) -> Integer

Get the error code.

C++ equivalent: Integer code() const

pub fn domain(&self) -> ErrorDomain

Get the error domain.

C++ equivalent: ErrorDomain domain() const

pub fn user_info(&self) -> *mut Dictionary

Get the user info dictionary.

C++ equivalent: class Dictionary* userInfo() const

pub fn localized_description(&self) -> *mut String

Get the localized description.

C++ equivalent: class String* localizedDescription() const

pub fn localized_recovery_options(&self) -> *mut Array<String>

Get the localized recovery options.

C++ equivalent: class Array* localizedRecoveryOptions() const

pub fn localized_recovery_suggestion(&self) -> *mut String

Get the localized recovery suggestion.

C++ equivalent: class String* localizedRecoverySuggestion() const

pub fn localized_failure_reason(&self) -> *mut String

Get the localized failure reason.

C++ equivalent: class String* localizedFailureReason() const

pub unsafe fn from_ptr(ptr: *mut c_void) -> Option<Self>

Create an Error from a raw pointer.

Safety

The pointer must be a valid Objective-C NSError object.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copying for Error

fn copy(&self) -> Option<Self>

Create a copy of this object.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl Referencing for Error

fn as_ptr(&self) -> *const c_void

Get the raw pointer to the Objective-C object.

fn as_mut_ptr(&self) -> *mut c_void

Get the raw mutable pointer to the Objective-C object.

fn retain(&self) -> Self

where Self: Clone,

Retain the object, incrementing its reference count.

fn release(&self)

Release the object, decrementing its reference count.

fn autorelease(&self) -> Self

where Self: Clone,

Autorelease the object.

fn retain_count(&self) -> UInteger

Get the retain count of the object.
