Enum ErrorKind

}

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].

Implementations

impl ErrorKind

pub fn as_str(self) -> &'static str

Short stable identifier, handy for tests and future diagnostics.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.
