Implementations

impl FermionicOperator

pub const fn is_creation(&self) -> bool

Check if operator is creation type

pub const fn is_annihilation(&self) -> bool

Check if operator is annihilation type

pub const fn site(&self) -> Option<usize>

Get site index for single-site operators

pub fn ordering_key(&self) -> (usize, usize)

Get canonical ordering for operator comparison

Trait Implementations

impl Clone for FermionicOperator

fn clone(&self) -> FermionicOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FermionicOperator

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

Formats the value using the given formatter.

impl Hash for FermionicOperator

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 PartialEq for FermionicOperator

fn eq(&self, other: &FermionicOperator) -> 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.
