pub trait IntoDart {
// Required method
fn into_dart(self) -> DartCObject;
}Expand description
A trait to convert between Rust types and Dart Types that could then be sent to the isolate
see: crate::Isolate::post
Required Methods§
Sourcefn into_dart(self) -> DartCObject
fn into_dart(self) -> DartCObject
Consumes Self and Performs the conversion.

⚠️ concatenated in a single Vec<u8> for performance optimization
on the other side of FFI, value should be reconstructed like:
-
hydrate into Dart List<UuidValue>
return List<UuidValue>.generate( raw.lengthInBytes / 16, (int i) => UuidValue.fromByteList(Uint8List.view(raw.buffer, i * 16, 16)), growable: false); -
hydrate into Rust Vec<Uuid>
ⓘraw .as_slice() .chunks(16) .map(|x: &[u8]| uuid::Uuid::from_bytes(*<&[u8] as std::convert::TryInto<&[u8;16]>>::try_into(x).expect("invalid uuid slice"))) .collect();
note that buffer could end up being incomplete under the same conditions as of std::io::Write::write.
