Struct VTFrameProcessorError 

#[repr(transparent)]
pub struct VTFrameProcessorError(pub NSInteger);

Available on crate features VTFrameProcessorErrors and objc2 only.

VTFrameProcessor error codes.

These error codes are returned in the NSError object in the event a method fails.

Implementations

impl VTFrameProcessorError

pub const UnknownError: Self

Returned if the processor failed for unknown reason.

pub const UnsupportedResolution: Self

Returned if the processor failed due to an unsupported resolution.

pub const SessionNotStarted: Self

Returned if the session is used to process frames without being started.

pub const SessionAlreadyActive: Self

Returned if a startSessionWithConfiguration call is made on a session which has already been started.

pub const FatalError: Self

Returned if a fatal error is encoutnered during processing.

pub const SessionLevelError: Self

Returned if processing failed and current session should be stopped.

pub const InitializationFailed: Self

Returned if the session failed to initialize the processing pipeline.

pub const UnsupportedInput: Self

Returned to indicate that one or more frames is in a format which is not supproted by the processor.

pub const MemoryAllocationFailure: Self

Returned if the session or processor is unable to allocate required memory.

pub const RevisionNotSupported: Self

Returned if the specifed revision is not supported by the configured processor.

pub const ProcessingError: Self

Returned if the processor encountered an issue preventing it from processing the provided frame.

pub const InvalidParameterError: Self

Returned if one of the provided parameters is not valid.

pub const InvalidFrameTiming: Self

Returned if one of the provided VTFrameProcessorFrame objects has a presentation time which is not supported by the processor, either invalid or out-of-order.

pub const AssetDownloadFailed: Self

Returned if download of a required model asset for the processor failed

Trait Implementations

impl Clone for VTFrameProcessorError

fn clone(&self) -> VTFrameProcessorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VTFrameProcessorError

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

Formats the value using the given formatter.

impl Encode for VTFrameProcessorError

const ENCODING: Encoding = NSInteger::ENCODING

The Objective-C type-encoding for this type.

impl Hash for VTFrameProcessorError

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 VTFrameProcessorError

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

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

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

const ENCODING_REF: Encoding

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

impl Copy for VTFrameProcessorError

impl Eq for VTFrameProcessorError

impl StructuralPartialEq for VTFrameProcessorError
