Enum Then 

#[non_exhaustive]
pub enum Then {
    Drop,
    Step,
    Sleep,
}

A behavior’s request for what should happen to it next.

Returned from Behavior::step(). Analogous to core::task::Poll for futures.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Drop

Remove the behavior from the behavior set, and never call it again.

Step

Step again upon the next tick.

Sleep

Don’t step until the Context::waker() is invoked.

Trait Implementations

impl Clone for Then

fn clone(&self) -> Then

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Then

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Then

fn eq(&self, other: &Then) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
