Mojo struct

Pointer

Defines a non-nullable safe pointer.

Parameters​

  • ​is_mutable (Bool): Whether the pointee data may be mutated through this.
  • ​type (AnyType): Type of the underlying data.
  • ​origin (Origin[is_mutable.value]): The origin of the pointer.
  • ​address_space (AddressSpace): The address space of the pointee data.

Implemented traits​

AnyType, CollectionElementNew, Copyable, ExplicitlyCopyable, Movable, Stringable

Methods​

__init__​

__init__(out self, *, other: Self)

Constructs a copy from another Pointer.

Note that this does not copy the underlying data.

Args:

  • ​other (Self): The Pointer to copy.

__getitem__​

__getitem__(self) -> ref [origin, address_space] type

Enable subscript syntax ptr[] to access the element.

Returns:

A reference to the underlying value in memory.

__eq__​

__eq__(self, rhs: Pointer[type, origin, address_space]) -> Bool

Returns True if the two pointers are equal.

Args:

  • ​rhs (Pointer[type, origin, address_space]): The value of the other pointer.

Returns:

True if the two pointers are equal and False otherwise.

__ne__​

__ne__(self, rhs: Pointer[type, origin, address_space]) -> Bool

Returns True if the two pointers are not equal.

Args:

  • ​rhs (Pointer[type, origin, address_space]): The value of the other pointer.

Returns:

True if the two pointers are not equal and False otherwise.

address_of​

static address_of(ref [origin, address_space] value: type) -> Self

Constructs a Pointer from a reference to a value.

Args:

  • ​value (type): The value to get the address of.

Returns:

The result Pointer.

__str__​

__str__(self) -> String

Gets a string representation of the Pointer.

Returns:

The string representation of the Pointer.
