Struct Request 

pub struct Request {
    pub data: Option<Vec<BufferRegion>>,
    pub defer_completion: Option<bool>,
    pub information: Option<RequestInfo>,
    pub short: Option<bool>,
    /* private fields */
}

Requests passed over fuchsia.hardware.usb.endpoint.Endpoint. See fuchsia.hardware.usb.endpoint.Endpoint::QueueRequests for more details.

Fields

data: Option<Vec<BufferRegion>>

Data. This array is consumed in-order, and allows for scatter/gather semantics across physically non-contiguous regions of a large buffer.

defer_completion: Option<bool>

Indicates not to complete this Request when done unless it failed. All Requests up to the next defer_completion == false are responded to as one unit.

information: Option<RequestInfo>

Extra information needed for Request.

short: Option<bool>

True if this is a short transfer sending less than what the receiver is expecting. Controllers ensure this transfer is terminated by a short packet.

Interpreted as false if absent.

Trait Implementations

impl Debug for Request

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

Formats the value using the given formatter.

impl Decode<Request, DefaultFuchsiaResourceDialect> for Request

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<'_, DefaultFuchsiaResourceDialect>, offset: usize, depth: Depth, ) -> Result<()>

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

impl Default for Request

fn default() -> Request

Returns the “default value” for a type.

impl Encode<Request, DefaultFuchsiaResourceDialect> for &mut Request

unsafe fn encode( self, encoder: &mut Encoder<'_, DefaultFuchsiaResourceDialect>, 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 Request

fn eq(&self, other: &Request) -> 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 ResourceTypeMarker for Request

type Borrowed<'a> = &'a mut Request

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

fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>

Cheaply converts from &mut Self::Owned to Self::Borrowed. For HandleBased types this is “take” (it returns an owned handle and replaces value with Handle::invalid), and for all other types it is “borrow” (just converts from one reference to another).

impl Standalone<DefaultFuchsiaResourceDialect> for Request

impl StructuralPartialEq for Request

impl TypeMarker for Request

type Owned = Request

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.
