Struct Generator 

pub struct Generator { /* private fields */ }

A generator produced by a generator function.

Generator are functions or closures which contain the yield expressions.

Examples

use std::ops::generator::Generator;

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

let g = f(10);

assert!(g is Generator);

Implementations

impl Generator

pub fn next(&mut self) -> Result<Option<Value>, VmError>
