Rejection reason for presentation documents, topology, or input.

Variants

InvalidIdentifier

An identifier is empty, too long, or contains unsupported characters.

InvalidMonoView

A target has a monoscopic viewport with a non-monoscopic identity.

InvalidStereoViews

A stereo target does not declare one left and one right viewport.

EmptyViewport

A target surface or viewport has zero dimensions.

ViewportOutOfBounds

A viewport extends outside the declared target surface.

OverlappingStereoViewports

Stereo viewports occupy overlapping regions.

TooManyNodes

A document exceeds its node bound.

DuplicateNodeId

More than one node uses an identifier.

UnresolvedRoomAnchor

A world placement’s anchor is absent from the resolved adapter context.

InvalidRoomAnchorTransform

A resolved room anchor has a nonfinite or non-rigid transform.

TextTooLong

Node text or labels exceed their portable bound.

InvalidSlider

A slider’s values or step are malformed.

InvalidTextInput

A text input’s current value exceeds its declared bound.

WrongDocument

An event names another document.

StaleRevision

An event targets an older or newer document revision.

UnknownNode

An event names no node in the document.

DisabledNode

An event targets a disabled node.

WrongEventForNode

The event kind or action does not match the node role.

SliderValueOutOfRange

A slider event is nonfinite, outside range, or misses its step.

TextValueTooLong

A text input event exceeds the node’s declared bound.

Trait Implementations

impl Clone for PresentationError

fn clone(&self) -> PresentationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PresentationError

impl Debug for PresentationError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PresentationError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PresentationError

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

Formats the value using the given formatter.

impl Eq for PresentationError

impl Error for PresentationError

Available on crate feature std only.

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 PartialEq for PresentationError

fn eq(&self, other: &PresentationError) -> 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 Serialize for PresentationError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
