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.

Returned if the processor failed for unknown reason.

Returned if the processor failed due to an unsupported resolution.

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

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

Returned if a fatal error is encoutnered during processing.

Returned if processing failed and current session should be stopped.

Returned if the session failed to initialize the processing pipeline.

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

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

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

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

Returned if one of the provided parameters is not valid.

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

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
