Mojo trait

IntableRaising

The IntableRaising trait describes a type can be converted to an Int, but the conversion might raise an error.

Any type that conforms to Intable or IntableRaising can construct an Int.

This trait requires the type to implement the __int__() method, which can raise an error. For example:

struct Foo(IntableRaising):
    var i: Int

    fn __int__(self) raises -> Int:
        return self.i

Now you can construct an Int:

foo = Foo(42)
assert_equal(Int(foo), 42)

Implemented traits

alias __del__is_trivial

A flag (often compiler generated) to indicate whether the implementation of __del__ is trivial.

The implementation of __del__ is considered to be trivial if:

The struct has a compiler-generated trivial destructor and all its fields have a trivial __del__ method.

In practice, it means that the __del__ can be considered as no-op.

__int__(self: _Self) -> Int

Get the integral representation of the value.

Returns:

Int: The integral representation of the type.

Raises:

If the type does not have an integral representation.
