Struct LocalOccupationConstraint 

pub struct LocalOccupationConstraint { /* private fields */ }

Site-local constraint for packed binary species.

A local state is encoded as a bit mask over species: bit s is the occupation of species s at the site. This represents exclusions such as no-double-occupancy without embedding a model-specific predicate in the fermion basis or an interop layer.

Implementations

impl LocalOccupationConstraint

pub fn new( species: usize, allowed_local_states: impl IntoIterator<Item = usize>, ) -> Result<Self>

pub const fn species(&self) -> usize

pub fn allowed_local_states(&self) -> &[usize]

pub fn accepts_packed_state(&self, state: u128, sites: usize) -> Result<bool>

Trait Implementations

impl Clone for LocalOccupationConstraint

fn clone(&self) -> LocalOccupationConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocalOccupationConstraint

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

Formats the value using the given formatter.

impl PartialEq for LocalOccupationConstraint

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