Struct QuantumMetric 

pub struct QuantumMetric(/* private fields */);

Quantum Metric component ($g_{ij}$).

Represents the real symmetric part of the Quantum Geometric Tensor. It measures the “distance” between quantum states in parameter space.

• Dimensions: Usually dimensionless (if $k$ is dimensionless) or $L^2$.

Implementations

impl QuantumMetric

pub fn new(val: f64) -> Result<Self, PhysicsError>

pub fn value(&self) -> f64

Trait Implementations

impl Clone for QuantumMetric

fn clone(&self) -> QuantumMetric

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuantumMetric

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

Formats the value using the given formatter.

impl Default for QuantumMetric

fn default() -> QuantumMetric

Returns the “default value” for a type.

impl From<QuantumMetric> for f64

fn from(val: QuantumMetric) -> Self

Converts to this type from the input type.

impl PartialEq for QuantumMetric

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

impl PartialOrd for QuantumMetric

fn partial_cmp(&self, other: &QuantumMetric) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
