Struct OperatorSpec 

pub struct OperatorSpec { /* private fields */ }

One typed local operator product and its spatial couplings.

Implementations

impl OperatorSpec

pub fn new( label: impl AsRef<str>, couplings: impl IntoIterator<Item = Coupling>, ) -> Result<Self>

Parse a compact product label and attach its spatial couplings.

pub fn from_product( product: OpProduct, couplings: impl IntoIterator<Item = Coupling>, ) -> Result<Self>

Attach spatial couplings to a parsed local operator product.

Every coupling must have the same arity as product, and coefficients must be finite.

pub fn operator(&self) -> &str

Return the canonical compact operator label.

pub const fn product(&self) -> &OpProduct

Return the typed, parsed local product.

pub fn couplings(&self) -> &[Coupling]

Return the spatial couplings in insertion order.

pub fn with_site_permutation(&self, permutation: &[usize]) -> Result<Self>

Return the same local action after a bijective site relabeling.

permutation[old_site] is the site used by the returned term. This keeps frontend indexing conventions and lattice embeddings outside the universal assembler.

Trait Implementations

impl Clone for OperatorSpec

fn clone(&self) -> OperatorSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperatorSpec

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

Formats the value using the given formatter.

impl PartialEq for OperatorSpec

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