Struct syscall_encode::abi::registers_and_stack::RegistersAndStackEncoder

pub struct RegistersAndStackEncoder<'a, Abi, RegisterType, const NR_REGS: usize>where
    Abi: SyscallAbi,
    RegisterType: Copy + Default,{ /* private fields */ }

A basic encoder that encodes values byte-by-byte into registers, or the stack if we spill over. Somewhat slow, but can encode all the basic types. Can be configured by the register type (u32, u64, etc) and the number of registers that can be used as syscall arg registers.
