Enum Incomplete 

#[non_exhaustive]
pub enum Incomplete {
    Suspended,
    Cancelled(Cancelled),
    Exhausted,
}

The error type returned by an algorithm when the result is not (yet) available.

The result can be unavailable because the computation was canceled (Cancelled) or because the algorithm has not finished computing but reached one of its pre-defined suspend points.

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.

Suspended

The computation has reached a suspend point and can be resumed.

Cancelled(Cancelled)

The computation was canceled by an external cancellation token.

Exhausted

The computation has already completed and cannot produce more results.

This is returned when a crate::Computable or crate::Generatable is polled after it has already produced its final result.

Trait Implementations

impl Clone for Incomplete

fn clone(&self) -> Incomplete

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Incomplete

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

Formats the value using the given formatter.

impl Display for Incomplete

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

Formats the value using the given formatter.

impl Error for Incomplete

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Cancelled> for Incomplete

fn from(value: Cancelled) -> Self

Converts to this type from the input type.

impl Hash for Incomplete

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Incomplete

fn eq(&self, other: &Incomplete) -> 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.
