Expand description

The category of a runtime error. Each variant maps to a pls/oh no catchable failure a Doge program can hit.

Variants§

§

TypeError

An operator or builtin was handed a value of the wrong type.

§

DivisionByZero

/ or // or % with a zero divisor.

§

Overflow

A number too large to materialize where a bounded one is unavoidable — a ** exponent too big to compute, or a non-finite Float narrowed to an Int. Ordinary Int arithmetic is arbitrary precision and never overflows.

§

IndexOutOfBounds

List/Str index outside the valid range.

§

KeyError

Dict lookup for a key that is not present.

§

ValueError

A value was the right type but not a usable value (e.g. int("dog")).

§

IOError

An I/O or environment operation failed: a file could not be read/written, or held bytes that were not valid text.

§

AttrError

A missing field or method on an object, or a method call on a value whose type has no methods at all.

§

Bonk

A bonk raised by the program itself.

§

AssertError

An amaze assertion whose condition was falsy.

§

RecursionLimit

A call chain nested past [RECURSION_LIMIT].
