Enum RankOneTwo 

pub enum RankOneTwo<T: FloatExt + Hash> {
    Rank1(Rank1<T>),
    Rank2(Det1<T>),
}

Represents a 2×2 complex matrix of rank 1 or 2, in a compact structured form.

Variants

Rank1(Rank1<T>)

A rank-1 matrix of the formM = |ket⟩⟨bra|.

This variant encodes a matrix as the outer product of a normalized ket and bra.

Rank2(Det1<T>)

A full-rank 2×2 complex matrix with unit determinant.

The matrix is expressed in the Pauli (quaternion) basis, and may be Hermitian or non-Hermitian.

Implementations

impl<T: FloatExt + Hash> RankOneTwo<T>

pub fn dag(self) -> Self

Returns the Hermitian conjugate (dagger) of the matrix.

pub fn trace(self) -> Cpx<T>

Returns the trace of the matrix.

pub fn det(self) -> Cpx<T>

Returns the determinant of the matrix.

pub fn rank(self) -> usize

Returns the rank of this finite rank 2x2 matrix.

Trait Implementations

impl<T: Clone + FloatExt + Hash> Clone for RankOneTwo<T>

fn clone(&self) -> RankOneTwo<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + FloatExt + Hash> Debug for RankOneTwo<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Hash + FloatExt + Hash> Hash for RankOneTwo<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq + FloatExt + Hash> PartialEq for RankOneTwo<T>

fn eq(&self, other: &RankOneTwo<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
