More than one parameter was used for a generator.
Erroneous code example:
#![feature(generators, generator_trait)]
fn main() {
let generator = |a: i32, b: i32| {
// error: too many parameters for a generator
// Allowed only 0 or 1 parameter
yield a;
};
}At present, it is not permitted to pass more than one explicit parameter for a generator.This can be fixed by using at most 1 parameter for the generator. For example, we might resolve the previous example by passing only one parameter.
#![feature(generators, generator_trait)]
fn main() {
let generator = |a: i32| {
yield a;
};
}
