Struct quantum::registers::ClassicalRegister
[−]
[src]
pub struct ClassicalRegister {
// some fields omitted
}Represents a non-quantum register of width() bits.
We store this inefficiently for clarity.
Methods
impl ClassicalRegister[src]
fn new(bits: Vec<u8>) -> ClassicalRegister
Construct a new non-quantum register, given a vector of ones and zeroes.
The width is automatically determined from the vector.
fn from_state(width: usize, state: u32) -> ClassicalRegister
Construct a new non-quantum register, given a state.
See the state() method documentation for details of the encoding.
Panics
We assert that the state is valid for the given width.
fn from_int(width: usize, int: u32) -> ClassicalRegister
Construct a new non-quantum register, given an unsigned integer.
See the state() method documentation for details of the encoding.
Panics
We assert that the integer is valid for the width.
fn zeroed(width: usize) -> ClassicalRegister
Construct zero-initialized non-quantum register of given width.
fn width(&self) -> usize
Compute the register's width.
fn state(&self) -> u32
Compute the current state of the register.
The state is an integer which uniquely specifies all register bits (for a
given width). It does this in the obvious way, by enumerating all 2n bit
strings in the reversed lexicographic order, and assigning each string an index.
This is equivalent to interpreting the register as an integer with the leftmost bit of least significance.
Panics
This only works for registers of width <= 32.
fn to_int(&self) -> u32
Return the integer represented by this register.
See the state() method documentation for details of the encoding.
