Enum Data
pub enum Data {
Viewport(Viewport),
PointerSample(PointerSample),
// some variants omitted
}
Expand description
A selection of FIFO data sent over the channel. Each data may have a different issuance policy.
Variants§
Viewport(Viewport)
The parameters of the viewport, sufficient for a client to correctly interpret the position and scale of pointer events dispatched to it.
- It is issued on every change to the viewport.
PointerSample(PointerSample)
A description of each sampled data point in a pointer event stream.
- It is issued on every sample in the pointer event stream.

§fn inline_align(_context: Context) -> usize
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
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. Read more§fn decode_is_copy() -> bool
