Enum OpenError

pub enum OpenError {
    InstanceNotFound,
    BadMoniker,
    InstanceNotResolved,
    InstanceNotRunning,
    FidlError,
    NoSuchDir,
    BadDirType,
    BadPath,
    InstanceFailedToStart,
    InstanceDestroyed,
    // some variants omitted
}

Errors that can be returned by the OpenDirectory call.

Variants

InstanceNotFound

Could not find an instance matching the given moniker.

BadMoniker

The given moniker could not be parsed.

InstanceNotResolved

The requested directory is available when the instance is resolved.

InstanceNotRunning

The requested directory is available when the instance is running.

Deprecation: the platform will stop emitting this error from version 19. The component will always be started if not already.

FidlError

Component manager’s open request on the directory returned a FIDL error.

NoSuchDir

The instance does not have a directory of this type.

BadDirType

The given directory type could not be parsed.

BadPath

The given path could not be parsed by component manager.

InstanceFailedToStart

Serving the requested directory requires starting the instance, but the instance failed to start.

InstanceDestroyed

Instance matching moniker was destroyed.

Implementations

impl OpenError

pub fn from_primitive(prim: u32) -> Option<Self>

pub fn from_primitive_allow_unknown(prim: u32) -> Self

pub fn unknown() -> Self

pub const fn into_primitive(self) -> u32

pub fn is_unknown(&self) -> bool

Trait Implementations

impl Clone for OpenError

fn clone(&self) -> OpenError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpenError

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

Formats the value using the given formatter.

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

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<OpenError, D> for OpenError

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 OpenError

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 OpenError

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

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

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

type Owned = OpenError

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 OpenError

type Borrowed<'a> = OpenError

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.
