Module gazebo::cast

Cast between types with no conversion.

Most of these operations are inherently unsafe, but provided as strongly-typed wrappers to reduce the chance of typos ending up with even more unsafe functions. If you use the result in incorrect ways, it will cause undefined behaviour.

Functions

ptr^⚠

Undefined behaviour if the argument does not satisfy the alignment of type To.

ptr_lifetime^⚠

ptr_mut^⚠

Undefined behaviour if the argument does not satisfy the alignment of type To.

ptr_to_usize

transmute_unchecked^⚠

Like normal transmute, but without the compile-time check that the sizes of the input and output are the same. Despite the removal of the compile-time check, this property must still hold, and there is a debug_assert_eq which checks that. All the rules and warnings from transmute still apply.

usize_to_ptr^⚠

Undefined behaviour if the argument is zero, or does not satisfy the alignment of type T.
