Expand description

Structured error codes for elaboration failures.

Variants§

UnknownName

A name was not found in scope.

TypeMismatch

Type mismatch: expected vs. actual type differ.

UnsolvedMvar

A metavariable could not be solved.

AmbiguousInstance

Multiple typeclass instances match.

NoInstance

No typeclass instance found.

UnificationFailed

Unification failed.

IllTyped

Expression is ill-typed.

TacticFailed

Tactic execution failed.

NonExhaustiveMatch

Pattern matching is not exhaustive.

SyntaxError

Syntax error (propagated from parser).

KernelRejected

The kernel rejected the term.

SorryNotAllowed

Sorry was used but not allowed.

RecursionLimit

Recursion limit exceeded.

MutualCycle

Mutual recursion cycle detected.

Other

Other/unclassified error.

Trait Implementations§

impl Clone for ElabErrorCode

fn clone(&self) -> ElabErrorCode

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for ElabErrorCode

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

Formats the value using the given formatter. Read more

impl Display for ElabErrorCode

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

Formats the value using the given formatter. Read more

impl PartialEq for ElabErrorCode

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

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
