Expand description
The various kinds of allowed errors.
Variants§
Unknown
An unknown error has occurred.
If this happens, it is a bug.
StackOverflow
The stack has overflowed.
OutOfBounds
There was an out-of-bounds array access.
IntegerOverflow
An integer operation caused an overflow to happen.
IntegerDivisonByZero
An integer operation caused a division-by-zero to happen.
BadConversionToInteger
A float-to-integer conversion failed.
UserGenerated
User generated error.
