Implementations

impl AXError

pub const Success: Self

No error occurred.

pub const Failure: Self

A system error occurred, such as the failure to allocate an object.

pub const IllegalArgument: Self

An illegal argument was passed to the function.

pub const InvalidUIElement: Self

The AXUIElementRef passed to the function is invalid.

pub const InvalidUIElementObserver: Self

The AXObserverRef passed to the function is not a valid observer.

pub const CannotComplete: Self

The function cannot complete because messaging failed in some way or because the application with which the function is communicating is busy or unresponsive.

pub const AttributeUnsupported: Self

The attribute is not supported by the AXUIElementRef.

pub const ActionUnsupported: Self

The action is not supported by the AXUIElementRef.

pub const NotificationUnsupported: Self

The notification is not supported by the AXUIElementRef.

pub const NotImplemented: Self

Indicates that the function or method is not implemented (this can be returned if a process does not support the accessibility API).

pub const NotificationAlreadyRegistered: Self

This notification has already been registered for.

pub const NotificationNotRegistered: Self

Indicates that a notification is not registered yet.

pub const APIDisabled: Self

The accessibility API is disabled (as when, for example, the user deselects “Enable access for assistive devices” in Universal Access Preferences).

pub const NoValue: Self

The requested value or AXUIElementRef does not exist.

pub const ParameterizedAttributeUnsupported: Self

The parameterized attribute is not supported by the AXUIElementRef.

pub const NotEnoughPrecision: Self

Not enough precision.

Trait Implementations

impl Clone for AXError

fn clone(&self) -> AXError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AXError

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

Formats the value using the given formatter.

impl Encode for AXError

Available on crate feature objc2 only.

const ENCODING: Encoding = i32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AXError

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 AXError

fn cmp(&self, other: &AXError) -> 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 AXError

fn eq(&self, other: &AXError) -> 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 AXError

fn partial_cmp(&self, other: &AXError) -> 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 AXError

Available on crate feature objc2 only.

const ENCODING_REF: Encoding

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

impl Copy for AXError

impl Eq for AXError

impl StructuralPartialEq for AXError
