Variants§
UndefinedVariable
A variable lookup operation failed. name holds the name of the variable that was expected.
Fields
name: CompactStringUndefinedCostume
A name-based costume lookup operation failed.
Fields
name: CompactStringUndefinedSound
A name-based sound lookup operation failed.
Fields
name: CompactStringUndefinedEntity
A name-based entity lookup operation failed.
Fields
name: CompactStringUpvarAtRoot
An upvar was created at the root scope, which is not allowed (it has nothing to refer up to).
ConversionError
The result of a failed type conversion.
VariadicConversionError
The result of a failed variadic type conversion (expected type T or a list of type T).
Incomparable
Attempt to compare incomparable types.
EmptyList
An operation that expected a non-empty list received an empty list as input.
InvalidListLength
An operation that expected a list with a certain size received an incorrect size.
IndexOutOfBounds
An indexing operation on a list/string had an out of bounds index, index, on a list/string of size len. Note that Snap!/NetsBlox use 1-based indexing.
IndexNotInteger
Attempt to index a list with a non-integer numeric value, index.
NoteNotInteger
Attempt to create a MIDI note value which was not an integer.
NoteNotMidi
Attempt to create a MIDI note with a value outside the allowed MIDI range.
Fields
note: CompactStringInvalidSize
Attempt to use a number which was not a valid size (must be convertible to usize).
InvalidUnicode
Attempt to interpret an invalid unicode code point (number) as a character.
CallDepthLimit
Exceeded the maximum call depth.
ClosureArgCount
Attempt to call a closure which required expected arguments, but got arguments were supplied.
CyclicValue
An acyclic operation received a cyclic input value.
NotCsv
Attempt to parse an invalid CSV-encoded string.
Fields
value: CompactStringNotJson
Attempt to parse an invalid JSON-encoded string.
Fields
value: CompactStringToSimpleError
A failed attempt to convert a native vm Value to SimpleValue.
Fields
error: ToSimpleError<C, S>IntoJsonError
A failed attempt to convert a SimpleValue to Json.
Fields
error: IntoJsonError<C, S>FromJsonError
A failed attempt to convert a Json value into a SimpleValue for use in the vm.
Fields
error: FromJsonErrorFromNetsBloxJsonError
A failed attempt to convert a Json value from NetsBlox into a SimpleValue for use in the vm.
Fields
error: FromNetsBloxJsonErrorNumberError
A numeric value took on an invalid value such as NaN.
Fields
error: NumberErrorNotSupported
Attempt to use an unsupported feature.
Promoted
A soft error (e.g., RPC or syscall failure) was promoted to a hard error.
Fields
error: CompactStringCustom
A custom error generated explicitly from user code.
