NotAReferenceSet(Sctid)

A ^ focus is not a reference set with members in the edition.

UnknownScheme(String)

An alternate identifier scheme alias resolves to no identifier scheme.

UnknownIdentifier

An alternate identifier names no concept.

Fields

scheme: String

The scheme alias.

code: String

The code.

UnknownField

A reference set has no field of the name.

Fields

refset: Sctid

The reference set.

field: String

The field.

Unsupported(&'static str)

A construct the edition’s data cannot answer.

UnknownDialect(String)

Trait Implementations

impl Clone for EvalError

fn clone(&self) -> EvalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Eq for EvalError

impl Error for EvalError

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 EvalError

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

Equality operator ==.

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

Inequality operator !=.
