Enum Indeterminacy 

#[non_exhaustive]
pub enum Indeterminacy {
    MissingInputs {
        missing: u32,
        ambiguous: u32,
    },
    UnresolvedConformations,
    Frame {
        frame: usize,
        reason: Box<Indeterminacy>,
    },
    Other(Box<str>),
}

Why no defensible answer exists under a policy.

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.

MissingInputs

The policy refuses to compute over atoms that are missing or ambiguous.

Fields

missing: u32

Intended atoms that were absent.

ambiguous: u32

Intended atoms that were present but not uniquely resolvable.

UnresolvedConformations

The alternate-conformation rule could not select a consistent set of atoms.

Frame

One frame of a series had no defensible answer, so the series has none.

Fields

frame: usize

Zero-based frame index.

reason: Box<Indeterminacy>

Why that frame has none.

Other(Box<str>)

A reason supplied by the analysis itself.

Trait Implementations

impl Clone for Indeterminacy

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Indeterminacy

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

Formats the value using the given formatter.

impl Display for Indeterminacy

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

Formats the value using the given formatter.

impl Eq for Indeterminacy

impl Error for Indeterminacy

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 PartialEq for Indeterminacy

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

Equality operator ==.

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

Inequality operator !=.
