Implementations

impl BGTaskSchedulerErrorCode

pub const Unavailable: Self

A task scheduling error indicating that the app or extension can’t schedule background work.

This error usually occurs for one of following reasons:

• The user has disabled background refresh in settings.
• The app is running on Simulator which doesn’t support background processing.
• The keyboard extension either hasn’t set <doc ://com.apple.documentation/documentation/bundleresources/information_property_list/nsextension/nsextensionattributes/requestsopenaccess> to YES in The Info.plist File, or the user hasn’t granted open access.
• The extension type isn’t able to schedule background tasks.

pub const TooManyPendingTaskRequests: Self

A task scheduling error indicating that there are too many pending tasks of the type requested.

Try canceling some existing task requests and then resubmit the request that failed.

pub const NotPermitted: Self

A task scheduling error indicating the app isn’t permitted to schedule the task.

There are four causes for this error:

• The app doesn’t set the appropriate mode in the <doc ://com.apple.documentation/documentation/bundleresources/information_property_list/uibackgroundmodes> array.
• The task identifier of the submitted task wasn’t in the <doc ://com.apple.documentation/documentation/bundleresources/information_property_list/bgtaskschedulerpermittedidentifiers> array in the Info.plist.
• The task requested additional BGContinuedProcessingTaskRequestResources that are unavailable.
• The user has explicitly denied background launches for your app.

pub const ImmediateRunIneligible: Self

A BGContinuedProcessingTaskRequest was not allowed to immediately run due to system conditions.

This will only be returned when using the BGContinuedProcessingTaskRequestSubmissionStrategyFail when submitting a BGContinuedProcessingTaskRequest. Task requests that are successfully ran will not be associated with any error code.

Trait Implementations

impl Clone for BGTaskSchedulerErrorCode

fn clone(&self) -> BGTaskSchedulerErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BGTaskSchedulerErrorCode

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

Formats the value using the given formatter.

impl Encode for BGTaskSchedulerErrorCode

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for BGTaskSchedulerErrorCode

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for BGTaskSchedulerErrorCode

fn cmp(&self, other: &BGTaskSchedulerErrorCode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BGTaskSchedulerErrorCode

fn eq(&self, other: &BGTaskSchedulerErrorCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for BGTaskSchedulerErrorCode

fn partial_cmp(&self, other: &BGTaskSchedulerErrorCode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefEncode for BGTaskSchedulerErrorCode

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.
