Enum OperationError

pub enum OperationError {
    Invalid,
    Failed,
    Unsupported,
    // some variants omitted
}

Fuchsia test harness operation error type.

A harness is responsible for maintaining the state for a particular test run. This type is returned when an operation fails.

Variants

Invalid

The requested operation is invalid.

This is returned when a test case asked the harness to do something incompatible with the harness’ current state. This error signifies a bug in the test code itself.

Returning this value MUST fail the corresponding test.

Example: Test asked for the size of a file before it was created.

Failed

The requested operation failed.

This is returned when the test harness failed to complete an operation, even though the current state should have permitted the operation to work. This error signifies a bug in a dependency of the harness.

Returning this value MUST fail the corresponding test.

Example: Test asked for the size of a file after it was created, but the query failed.

Unsupported

The requested operation is not supported by this harness.

This is returned when the test harness does not support the requested operation. This is not necessarily a fatal error, it is used to signify that the harness has knowledge of what was requested, but it does not implement the behavior.

Returning this value MAY fail the corresponding test, but it does not need to. This return value is useful to determine compatibility with different feature sets or versions.

Example: Test asked for the size of a file, but the ability to check file sizes was removed in the previous component version.

Trait Implementations

impl Clone for OperationError

fn clone(&self) -> OperationError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OperationError

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

Formats the value using the given formatter.

impl<D> Decode<OperationError, D> for OperationError

where D: ResourceDialect,

fn new_empty() -> OperationError

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<(), Error>

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

impl<D> Encode<OperationError, D> for OperationError

where D: ResourceDialect,

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

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

impl Hash for OperationError

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 OperationError

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

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

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

type Owned = OperationError

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 OperationError

type Borrowed<'a> = OperationError

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: &<OperationError as TypeMarker>::Owned, ) -> <OperationError as ValueTypeMarker>::Borrowed<'_>

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