pub struct DictionaryOptionalItem {
pub key: String,
pub value: Option<Box<WrappedCapabilityId>>,
}
Expand description
A key-value pair in a DictionaryRef
, where the value may be elided.
This is useful for APIs that may wish to omit the value, for example if it could not be
duplicated.

Source§type Borrowed<'a> = &'a mut DictionaryOptionalItem
type Borrowed<'a> = &'a mut DictionaryOptionalItem
The Rust type to use for encoding. This is a particular
Encode<Self>
type cheaply obtainable from &mut Self::Owned
. There are three cases: Read moreSource§fn take_or_borrow<'a>(
value: &'a mut <Self as TypeMarker>::Owned,
) -> Self::Borrowed<'a>
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).Source§impl TypeMarker for DictionaryOptionalItem

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

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
