Struct ScreenshotTakeFileResponse

pub struct ScreenshotTakeFileResponse {
    pub file: Option<ClientEnd<FileMarker>>,
    pub size: Option<SizeU>,
    /* private fields */
}

Fields

file: Option<ClientEnd<FileMarker>>

|fuchsia.io.File| channel used to read the generated screenshot file data. The server side of the channel is stored on the device until ZX_CHANNEL_PEER_CLOSED is detected.

Basic usage: After the client recieves the client end of the file channel, to avoid memory pile-ups, it should finish reading the data before calling [TakeFile] again. When finished reading, the client should call [Close] on the |fuchsia.io.File| channel, this will release the memory allocated on the server side.

size: Option<SizeU>

Size of the screenshot in pixels.

Trait Implementations

impl Debug for ScreenshotTakeFileResponse

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

Formats the value using the given formatter.

impl Decode<ScreenshotTakeFileResponse, DefaultFuchsiaResourceDialect> for ScreenshotTakeFileResponse

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 ScreenshotTakeFileResponse

fn default() -> ScreenshotTakeFileResponse

Returns the “default value” for a type.

impl Encode<ScreenshotTakeFileResponse, DefaultFuchsiaResourceDialect> for &mut ScreenshotTakeFileResponse

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 ScreenshotTakeFileResponse

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

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

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 TypeMarker for ScreenshotTakeFileResponse

type Owned = ScreenshotTakeFileResponse

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.
