Trait allo_isolate::IntoDart

source ·

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§

source

fn into_dart(self) -> DartCObject

Consumes Self and Performs the conversion.

Implementations on Foreign Types§

source §

fn into_dart(self) -> DartCObject

on the other side of FFI, value should be reconstructed like:

hydrate into Dart DateTime DateTime.fromMicrosecondsSinceEpoch(raw, isUtc: true);

hydrate into Rust DateTime::<Utc>

let s = (raw / 1_000_000) as i64;
let ns = (raw.rem_euclid(1_000_000) * 1_000) as u32;
chrono::DateTime::<chrono::Utc>::from_utc(
  chrono::NaiveDateTime::from_timestamp(s, ns), chrono::Utc);

note that it could overflow under the same conditions as of chrono::NaiveDateTime::from_timestamp

fn into_dart(self) -> DartCObject

impl IntoDart for Uuid

source §

fn into_dart(self) -> DartCObject

delegate to Vec<u8> implementation

on the other side of FFI, value should be reconstructed like:

hydrate into Dart UuidValue UuidValue.fromByteList(raw);

hydrate into Rust Uuid

uuid::Uuid::from_bytes(*<&[u8] as std::convert::TryInto<&[u8;16]>>::try_into(raw.as_slice()).expect("invalid uuid slice"));

impl IntoDart for Vec<Duration>

source §

fn into_dart(self) -> DartCObject

source §

impl<const N: usize> IntoDart for [f32; N]

source §

fn into_dart(self) -> DartCObject

source §

impl IntoDart for Vec<Uuid>

source §

fn into_dart(self) -> DartCObject

⚠️ 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.
