Implementations

impl AXError

pub const Success: Self

Available on crate feature HIServices only.

No error occurred.

pub const Failure: Self

Available on crate feature HIServices only.

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

pub const IllegalArgument: Self

Available on crate feature HIServices only.

An illegal argument was passed to the function.

pub const InvalidUIElement: Self

Available on crate feature HIServices only.

The AXUIElementRef passed to the function is invalid.

pub const InvalidUIElementObserver: Self

Available on crate feature HIServices only.

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

pub const CannotComplete: Self

Available on crate feature HIServices only.

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

Available on crate feature HIServices only.

The attribute is not supported by the AXUIElementRef.

pub const ActionUnsupported: Self

Available on crate feature HIServices only.

The action is not supported by the AXUIElementRef.

pub const NotificationUnsupported: Self

Available on crate feature HIServices only.

The notification is not supported by the AXUIElementRef.

pub const NotImplemented: Self

Available on crate feature HIServices only.

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

Available on crate feature HIServices only.

This notification has already been registered for.

pub const NotificationNotRegistered: Self

Available on crate feature HIServices only.

Indicates that a notification is not registered yet.

pub const APIDisabled: Self

Available on crate feature HIServices only.

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

Available on crate feature HIServices only.

The requested value or AXUIElementRef does not exist.

pub const ParameterizedAttributeUnsupported: Self

Available on crate feature HIServices only.

Trait Implementations

impl Clone for AXError

Available on crate feature HIServices only.

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

Available on crate feature HIServices only.

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

Formats the value using the given formatter.

impl Encode for AXError

Available on crate features HIServices and objc2 only.

const ENCODING: Encoding = i32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for AXError

Available on crate feature HIServices only.

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

Available on crate feature HIServices only.

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

Available on crate feature HIServices only.

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

Available on crate feature HIServices only.

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 features HIServices and objc2 only.

const ENCODING_REF: Encoding

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

impl Copy for AXError

Available on crate feature HIServices only.

impl Eq for AXError

Available on crate feature HIServices only.

impl StructuralPartialEq for AXError

Available on crate feature HIServices only.
