pub struct StackSlot(_);
Expand description

An opaque reference to a stack slot.

Stack slots represent an address on the call stack.

StackSlots can be created with FunctionBuilder::create_stackslot.

StackSlots are most often used with stack_addr, stack_load, and stack_store.

While the order is stable, it is arbitrary and does not necessarily resemble the stack order.

Implementations§
