Struct Isolate

pub struct Isolate { /* private fields */ }

Simple wrapper around the Dart Isolate Port, nothing else.

Implementations

impl Isolate

pub const fn new(port: i64) -> Self

Create a new Isolate with a port obtained from Dart VM side.

Example

this a non realistic example lol :D

let isolate = Isolate::new(42);

pub fn post(&self, msg: impl IntoDart) -> bool

Post an object to the Isolate over the port Object must implement IntoDart.

returns true if the message posted successfully, otherwise false

Safety

This assumes that you called store_dart_post_cobject and we have access to the Dart_PostCObject function pointer also, we do check if it is not null.

Example

let isolate = Isolate::new(42);
isolate.post("Hello Dart !");

pub async fn task<T, R>(self, t: T) -> bool

where T: Future<Output = R> + Send + 'static, R: Send + IntoDart + 'static,

Consumes Self, Runs the task, await for the result and then post it to the Isolate over the port Result must implement IntoDart.

returns true if the message posted successfully, otherwise false

Safety

This assumes that you called store_dart_post_cobject and we have access to the Dart_PostCObject function pointer also, we do check if it is not null.

Example

use async_std::task;
let isolate = Isolate::new(42);
task::spawn(isolate.task(async { 1 + 2 }));

pub async fn catch_unwind<T, R>(self, t: T) -> Result<bool, Box<dyn Any + Send>>

where T: Future<Output = R> + Send + 'static, R: Send + IntoDart + 'static,

Similar to Isolate::task but with more logic to catch any panic and report it back
