pub enum HeapStyle {
    Dynamic {

        bound: Uimm64,
    },
}

Variants

Dynamic

Fields

bound_gv: GlobalValue

Global value providing the current bound of the heap in bytes.

A dynamic heap can be relocated to a different base address when it is grown.

Static

Fields

Heap bound in bytes. The offset-guard pages are allocated after the bound.

A static heap has a fixed base address and a number of not-yet-allocated pages before the offset-guard pages.
