pub fn alloc<VM: VMBinding>(

    offset: usize,
    semantics: AllocationSemantics
) -> Address
Expand description

Allocate memory for an object. For performance reasons, a VM should implement the allocation fast-path on their side rather than just calling this function.

If the VM provides a non-zero offset parameter, then the returned address will be such that the RETURNED_ADDRESS + offset is aligned to the align parameter.


  • mutator: The mutator to perform this allocation request.
  • size: The number of bytes required for the object.
  • align: Required alignment for the object.
  • offset: Offset associated with the alignment.
  • semantics: The allocation semantic required for the allocation.
