Mojo trait

DivModable

The DivModable trait describes a type that defines division and modulo operations returning both quotient and remainder.

Types that conform to DivModable will work with the builtin divmod function, which will return the same type as the inputs.

For example:

@fieldwise_init
struct Bytes(DivModable):
    var size: Int

    def __divmod__(self, other: Self) -> Tuple[Self, Self]:
        var quotient_int = self.size // other.size
        var remainder_int = self.size % other.size
        return (Bytes(quotient_int), Bytes(remainder_int))

Implemented traits

AnyType, Copyable, ImplicitlyCopyable, ImplicitlyDestructible, Movable

Required methods

__init__

__init__(out self: _Self, *, copy: _Self)

Create a new instance of the value by copying an existing one.

Args:

  • copy (_Self): The value to copy.

Returns:

_Self

__init__(out self: _Self, *, deinit take: _Self)

Create a new instance of the value by moving the value of another.

Args:

  • take (_Self): The value to move.

Returns:

_Self

__divmod__

__divmod__(self: _Self, denominator: _Self) -> Tuple[_Self, _Self]

Performs division and returns the quotient and the remainder.

Args:

  • denominator (_Self): The value to divide by.

Returns:

Tuple: A Tuple containing the quotient and the remainder.

Provided methods

copy

copy(self: _Self) -> _Self

Explicitly construct a copy of self, a convenience method for Self(copy=self) when the type is inconvenient to write out.

Returns:

_Self: A copy of this value.
