Expand description

Type of error encountered when parsing a script.

Some errors never appear when certain features are turned on. They still exist so that the application can turn features on and off without going through massive code changes to remove/add back enum variants in match statements.

Variants (Non-exhaustive)

This enum is marked as 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.

UnexpectedEOF

The script ends prematurely.

BadInput(LexError)

Error in the script text. Wrapped value is the lex error.

UnknownOperator(String)

An unknown operator is encountered. Wrapped value is the operator.

MissingToken(String, String)

Expecting a particular token but not finding one. Wrapped values are the token and description.

MissingSymbol(String)

Expecting a particular symbol but not finding one. Wrapped value is the description.

MalformedCallExpr(String)

An expression in function call arguments () has syntax error. Wrapped value is the error description (if any).

MalformedIndexExpr(String)

An expression in indexing brackets [] has syntax error. Wrapped value is the error description (if any).

Never appears under the no_index feature.

MalformedInExpr(String)

An expression in an in expression has syntax error. Wrapped value is the error description (if any).

Never appears under the no_object and no_index features combination.

MalformedCapture(String)

A capturing has syntax error. Wrapped value is the error description (if any).

Never appears under the no_closure feature.

DuplicatedProperty(String)

A map definition has duplicated property names. Wrapped value is the property name.

Never appears under the no_object feature.

DuplicatedSwitchCase

A switch case is duplicated.

DuplicatedVariable(String)

A variable name is duplicated. Wrapped value is the variable name.

WrongSwitchDefaultCase

The default case of a switch statement is not the last.

WrongSwitchCaseCondition

The case condition of a switch statement is not appropriate.

PropertyExpected

Missing a property name for custom types and maps.

Never appears under the no_object feature.

VariableExpected

Missing a variable name after the let, const, for or catch keywords.

Reserved(String)

An identifier is a reserved keyword.

MismatchedType(String, String)

An expression is of the wrong type. Wrapped values are the type requested and type of the actual result.

ExprExpected(String)

Missing an expression. Wrapped value is the expression type.

WrongDocComment

Defining a doc-comment in an appropriate place (e.g. not at global level).
