Struct MachineRegister 

pub struct MachineRegister { /* private fields */ }

MachineRegister is a datatype that can hold exactly the contents of a register with no additional semantic information.

MachineRegister is useful when you know data is the size of a register, but not its true data type. In the future it may be possible, useful, or necessary to change the implementation of MachineRegister, however, the semantics will remain. No use of MachineRegister should assume a particular Rust implementation or any semantics other this description.

Implementations

impl MachineRegister

pub fn as_capability_ptr(self) -> CapabilityPtr

Returns this MachineRegister as a CapabilityPtr.

If this MachineRegister contains a pointer with provenance and/or authority, the returned CapabilityPtr will have the same provenance and/or authority.

pub fn as_usize(self) -> usize

Returns this MachineRegister as a usize.

This is intended for use on MachineRegisters created from a usize, in which case the original usize will be returned. If this MachineRegister was created from a pointer, this returns the pointer’s address (without exposing provenance).

pub fn as_usize_32bit(self) -> usize

Returns this MachineRegister as a usize, 32 bits only.

This returns a usize, but only uses the lowest 32 bits from the MachineRegister. If there are upper bits, they are set to 0. This is useful for capturing only the lower 32 bits on a 64-bit machine.

This is intended for use on MachineRegisters created from a usize, in which case 32 bits of the original usize will be returned. If this MachineRegister was created from a pointer, this returns the lowest 32 bits of the pointer’s address (without exposing provenance).
