Struct fidl_fuchsia_ui_focus::FocusKoidChain

pub struct FocusKoidChain {
    pub focus_chain: Option<Vec<u64>>,
    /* private fields */
}

A FocusKoidChain serves almost the same purpose as a FocusChain, but is intended for applications that merely need to identify views in the chain and do not need to watch their state.

Fields

focus_chain: Option<Vec<u64>>

Implementations

impl FocusKoidChain

pub const EMPTY: Self = _

An empty table with every field set to None.

Trait Implementations

impl Clone for FocusKoidChain

fn clone(&self) -> FocusKoidChain

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FocusKoidChain

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

Formats the value using the given formatter.

impl Decodable for FocusKoidChain

fn new_empty() -> Self

Creates a new value of this type with an “empty” representation.

fn decode(&mut self, decoder: &mut Decoder<'_>, offset: usize) -> Result<()>

Decodes an object of this type from the decoder’s buffers into self. Callers must ensure that offset is a multiple of Layout::inline_align, and that decoder.buf has room for reading Layout::inline_size bytes at offset.

impl Encodable for FocusKoidChain

fn encode( &mut self, encoder: &mut Encoder<'_, '_>, offset: usize, recursion_depth: usize ) -> Result<()>

Encode the object into the buffer. Any handles stored in the object are swapped for Handle::INVALID. Callers must ensure that offset is a multiple of Layout::inline_align, and that encoder.buf has room for writing Layout::inline_size bytes at offset.

impl Layout for FocusKoidChain

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 the type’s alignment. Must be a multiple of inline_align.

fn supports_simple_copy() -> boolwhere Self: Sized,

Returns true iff the type can be encoded or decoded via simple copy.

impl PartialEq<FocusKoidChain> for FocusKoidChain

fn eq(&self, other: &FocusKoidChain) -> 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.
