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
BadInput(String)
Tuple Fields
0: String
Error in the script text. Wrapped value is the error message.
UnexpectedEOF
The script ends prematurely.
UnknownOperator(String)
Tuple Fields
0: 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.
MalformedCallExpr(String)
Tuple Fields
0: String
An expression in function call arguments ()
has syntax error. Wrapped value is the error description (if any).
MalformedIndexExpr(String)
Tuple Fields
0: 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)
Tuple Fields
0: 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.
DuplicatedProperty(String)
Tuple Fields
0: String
A map definition has duplicated property names. Wrapped value is the property name.
Never appears under the no_object
feature.
ForbiddenConstantExpr(String)
Tuple Fields
0: String

feature.
FnMissingName
Missing a function name after the fn
keyword.
