Variants

UnknownPredicate(Literal)

Contains the literal with the unknown predicate name.

InsufficientGroundness(Vec<Literal>)

Contains the relevant goals.

MaximumDepthExceeded(Vec<Literal>, usize)

Contains the goals when the max depth was exceeded.

BuiltinFailure(Literal, &'static str)

Contains the relevant literal (builtin call), and the name of the selected builtin.

InsufficientRules(Literal)

Contains the literal that didn’t match with any rule head.

InconsistentGroundnessSignature(Vec<Signature>)

Contains the set of inconsistent signatures.

NegationProof(Literal)

Proof of a negated literal was found.

Implementations

impl ResolutionError

pub fn get_diagnostic(self) -> Diagnostic<()>

Trait Implementations

impl Clone for ResolutionError

fn clone(&self) -> ResolutionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolutionError

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

Formats the value using the given formatter.

impl Display for ResolutionError

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

Formats the value using the given formatter.

impl Hash for ResolutionError

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 ResolutionError

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