Struct Stream

pub struct Stream<T = Vm>
where
    T: AsRef<Vm> + AsMut<Vm>,
{ /* private fields */ }

A stream produced by an async generator function.

Generator are async functions or closures which contain the yield expressions.

Examples

use std::stream::Stream;

let f = async |n| {
    yield n;
    yield n + 1;
};

let g = f(10);

assert!(g is Stream);

Implementations

impl<T> Stream<T>

where T: AsRef<Vm> + AsMut<Vm>,

pub async fn next(&mut self) -> VmResult<Option<Value>>

Get the next value produced by this stream.

pub async fn resume(&mut self, value: Value) -> VmResult<GeneratorState>

Resume the generator and return the next generator state.

impl Stream<&mut Vm>

pub fn into_owned(self) -> Stream<Vm>

Convert the current stream into one which owns its virtual machine.
