Function alloc_with_options

pub fn alloc_with_options<VM: VMBinding>(
    mutator: &mut Mutator<VM>,
    size: usize,
    align: usize,
    offset: usize,
    semantics: AllocationSemantics,
    options: AllocationOptions,
) -> Address

Allocate memory for an object.

This allocation function allows alternation to the allocation behaviors, specified by the crate::util::alloc::AllocationOptions. For example, one can allow overcommit the memory to go beyond the heap size without triggering a GC. This function can be used in certain cases where the runtime needs a different allocation behavior other than what the default alloc provides.

Arguments:

• 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.
• options: the allocation options to change the default allocation behavior for this request.
