Enum MembershipPinError 

#[non_exhaustive]
pub enum MembershipPinError {
    Cycle(CycleDetected),
    InvalidMembership(NodeTemplateInstanceMergeError),
    UnknownSelector(String),
    MissingSelector(String),
    AmbiguousSelector(String),
    UnreachableAssignment,
}

Why source membership choices could not be pinned to a static realization.

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.

Cycle(CycleDetected)

Input dataflow needed for pinning is cyclic.

InvalidMembership(NodeTemplateInstanceMergeError)

Membership registration is invalid.

UnknownSelector(String)

A requested selector does not exist.

MissingSelector(String)

A source selector has no supplied choice.

AmbiguousSelector(String)

A selector name is not unique.

UnreachableAssignment

Supplied choices cannot jointly occur.

Trait Implementations

impl Debug for MembershipPinError

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

Formats the value using the given formatter.

impl Display for MembershipPinError

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

Formats the value using the given formatter.

impl Error for MembershipPinError

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<CycleDetected> for MembershipPinError

fn from(source: CycleDetected) -> Self

Converts to this type from the input type.

impl From<NodeTemplateInstanceMergeError> for MembershipPinError

fn from(source: NodeTemplateInstanceMergeError) -> Self

Converts to this type from the input type.
