Errors returned by Control/CreateRingBuffer.

Variants

DeviceError

This device has encountered an error and can no longer be controlled.

WrongDeviceType

This device type does not support the method that was called.

AlreadyPending

The previous CreateRingBuffer call has not yet completed.

InvalidElementId

The required element_id is missing or does not refer to a RING_BUFFER element.

InvalidOptions

The required options is missing.

InvalidFormat

The required options.format is missing.

InvalidMinBytes

The required options.ring_buffer_min_bytes is missing.

InvalidRingBuffer

The required ring_buffer_server is missing.

AlreadyAllocated

An active RingBuffer instance already exists for this Control.

FormatMismatch

The device does not support the specified format.

BadRingBufferOption

The device cannot create a ring buffer with the specified options.

Other

The driver returned some other error. This call may be retried.

Implementations

Trait Implementations

impl Clone for ControlCreateRingBufferError

fn clone(&self) -> ControlCreateRingBufferError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ControlCreateRingBufferError

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<ControlCreateRingBufferError, D> for ControlCreateRingBufferError

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl<D: ResourceDialect> Encode<ControlCreateRingBufferError, D> for ControlCreateRingBufferError

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for ControlCreateRingBufferError

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 ControlCreateRingBufferError

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

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

fn partial_cmp(&self, other: &ControlCreateRingBufferError) -> 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 TypeMarker for ControlCreateRingBufferError

type Owned = ControlCreateRingBufferError

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for ControlCreateRingBufferError

type Borrowed<'a> = ControlCreateRingBufferError

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
