Struct fidl_fuchsia_ui_gfx::ImageArgs3

pub struct ImageArgs3 {
    pub width: u32,
    pub height: u32,
    pub import_token: BufferCollectionImportToken,
    pub buffer_collection_index: u32,
}

An image that is backed by a BufferCollection registered with Allocator.

Fields

width: u32

height: u32

import_token: BufferCollectionImportToken

Image creation requires an allocated BufferCollection registered with Allocator. import_token should be the other end of a BufferCollectionExportToken that is successfully registered. All clients of the specified BufferCollection must have set their constraints and buffers should be allocated before calling.

buffer_collection_index: u32

The index of the VMO from the BufferCollection that backs this image.

Trait Implementations

impl Debug for ImageArgs3

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

Formats the value using the given formatter.

impl Decode<ImageArgs3> for ImageArgs3

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

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

impl Encode<ImageArgs3> for &mut ImageArgs3

unsafe fn encode( self, encoder: &mut Encoder<'_>, 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<T0: Encode<u32>, T1: Encode<u32>, T2: Encode<BufferCollectionImportToken>, T3: Encode<u32>> Encode<ImageArgs3> for (T0, T1, T2, T3)

unsafe fn encode( self, encoder: &mut Encoder<'_>, 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<ImageArgs3> for ImageArgs3

fn eq(&self, other: &ImageArgs3) -> 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 ResourceTypeMarker for ImageArgs3

type Borrowed<'a> = &'a mut ImageArgs3

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 ImageArgs3

type Owned = ImageArgs3

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.
