§type Owned = OptionalUint32
type Owned = OptionalUint32
The owned Rust type which this FIDL type decodes into.
§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
