Struct fidl_fuchsia_io::Options

pub struct Options {
    pub attributes: Option<NodeAttributesQuery>,
    pub create_attributes: Option<MutableNodeAttributes>,
    /* private fields */
}

Options which can be used with Open3. Unlike Flags, these options are designed for specific use cases (e.g. to reduce round-trip latency when requesting attributes).

Fields

attributes: Option<NodeAttributesQuery>

Request a set of attributes to be sent with the OnRepresentation response. Has no effect if Flags.FLAG_SEND_REPRESENTATION is not set.

create_attributes: Option<MutableNodeAttributes>

Request a set of attributes to be set atomically when creating a new object. Requests will fail with ZX_ERR_INVALID_ARGS if neither Flags.FLAG_MAYBE_CREATE nor Flags.FLAG_MUST_CREATE are set (i.e. the creation is mode is Never).

Trait Implementations

impl Clone for Options

fn clone(&self) -> Options

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Options

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

Formats the value using the given formatter.

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

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 Default for Options

fn default() -> Options

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<Options, D> for &Options

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 PartialEq for Options

fn eq(&self, other: &Options) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeMarker for Options

type Owned = Options

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 Options

type Borrowed<'a> = &'a Options

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.
