impl Index<XReg> for MachineState

type Output = XRegVal

The returned type after indexing.

fn index(&self, reg: XReg) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Index<XReg> for Vm

type Output = XRegVal

The returned type after indexing.

fn index(&self, reg: XReg) -> &Self::Output

impl Ord for XReg

fn cmp(&self, other: &XReg) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self
