Enum pushgen::TryReduction

pub enum TryReduction<T> {
    Complete(T),
    Partial(T),
}

The result value of a try_* reduction.

A try_* reduction can either be partial, producing an intermediate value, or complete. Partial reductions can for instance be created when trying to reduce a spuriously stopping generator.

Variants

Implementations

impl<T> TryReduction<T>

pub fn is_complete(&self) -> bool

Check if the reduction is complete.

Examples

Basic usage:

use pushgen::TryReduction;
let x = TryReduction::Complete(());
assert!(x.is_complete());
assert!(!x.is_partial());

pub fn is_partial(&self) -> bool

Check if the reduction is partial.

Examples

Basic usage:

use pushgen::TryReduction;
let x = TryReduction::Partial(());
assert!(x.is_partial());
assert!(!x.is_complete());

pub fn unwrap(self) -> T

Get the underlying value, no matter if it’s complete or partial.

Examples

Basic usage:

use pushgen::TryReduction;
let complete = TryReduction::Complete(1);
assert_eq!(complete.unwrap(), 1);
let partial = TryReduction::Partial(2);
assert_eq!(partial.unwrap(), 2);
