Enum PlanError 

#[non_exhaustive]
pub enum PlanError {
    EmptyOrZeroWeight,
    Overflow,
    AlreadyInUse,
    NotALeaf,
    Unsupported,
    NotShareable,
    Finished,
    UnfinishedChildren,
    NoMoreStages,
    StageMismatch,
}

A phase plan that cannot be applied, or a lifecycle step out of order.

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.

EmptyOrZeroWeight

A split needs at least one part, and every weight must be positive.

Overflow

The weights’ sum or the job’s phase identifiers overflowed.

AlreadyInUse

The phase already counted work or planned children. Plan once, first.

NotALeaf

The phase has children; only a leaf has its own total.

Unsupported

This pulse cannot plan children.

NotShareable

This borrowed implementation cannot provide an owned pulse.

Finished

The phase already has an outcome.

UnfinishedChildren

Every child must finish before its parent.

NoMoreStages

Every declared stage has already run.

StageMismatch

A stage reservation does not match the next declaration in this sequence.

impl Eq for PlanError

impl Error for PlanError

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 Hash for PlanError

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

where __H: Hasher,

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 PlanError

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

Equality operator ==.

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

Inequality operator !=.
