Struct ViewHolderArgs

pub struct ViewHolderArgs {
    pub token: ViewHolderToken,
    pub debug_name: Option<String>,
}

Represents an attachment point for a subgraph within a larger scene graph. The ViewHolder can be attached to a Node as a child, and the contents of the linked View will become a child of the Node as well.

Each ViewHolder is linked to a paired View via a shared token pair.

Usually the ViewHolder and its associated View exist in separate processes. By combining them, the UI for an entire system can be built using content contributed from many different processes.

Fields

token: ViewHolderToken

debug_name: Option<String>

Trait Implementations

impl Debug for ViewHolderArgs

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

Formats the value using the given formatter.

impl Decode<ViewHolderArgs, DefaultFuchsiaResourceDialect> for ViewHolderArgs

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 Encode<ViewHolderArgs, DefaultFuchsiaResourceDialect> for &mut ViewHolderArgs

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<T0: Encode<ViewHolderToken, DefaultFuchsiaResourceDialect>, T1: Encode<Optional<UnboundedString>, DefaultFuchsiaResourceDialect>> Encode<ViewHolderArgs, DefaultFuchsiaResourceDialect> for (T0, T1)

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 ViewHolderArgs

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

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

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 ViewHolderArgs

type Owned = ViewHolderArgs

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.
