Errors possible because of implementation mistakes.

Variants

Utf8Error(Utf8Error)

Data was not utf8 compatible.

ValueError(ValueError<'a>)

A ValueError occurred during parsing.

UnknownRule(&'a str)

Tried to get a rule that does not exists.

UnknownLabel(&'a str)

Tried to get a label that does not exist.

MissingRoot

The non-terminal identified by ROOT_UUID could not be found.

MissingSPPFNode(SPPFNodeIndex)

An SPPF node that we expect to exist in the graph is inexplicably missing.

IncorrectSPPFType(Vec<&'a str>, Discriminant<SPPFNode<'a>>)

We expected a specific type of SPPF Node, but got another.

MissingGSSNode(NodeIndex<DefaultIx>)

A GSS node that we expect to exist in the graph is inexplicably missing.

MissingGSSEdge(EdgeIndex)

A GSS edge is inexplicably missing.

MissingAttribute(AttributeKey, Rc<GSSNode<'a>>)

An attribute that is expected to have been passed does not exist.

MissingContext(AttributeKey, Rc<GSSNode<'a>>)

An attribute that is expected to be in the context does not exist.

CompletedSlot(String)

Tried to do something with a completed slot

Fatal(&'a str)

Any generic fatal error for which we have no specific variant.

Trait Implementations

impl<'a> Debug for GLLImplementationError<'a>

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

Formats the value using the given formatter.

impl<'a> Display for GLLImplementationError<'a>

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

Formats the value using the given formatter.

impl<'a> Error for GLLImplementationError<'a>

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.
