Enum KineticEnergyKind 

pub enum KineticEnergyKind {
    Euclidean,
    ExactNormal,
    Microcanonical,
}

Selects the kinetic-energy form (and thus the integrator) used by [TransformedHamiltonian].

Variants

Euclidean

Standard Euclidean kinetic energy K = ½ ‖v‖². Uses the ordinary leapfrog integrator (velocity Verlet).

ExactNormal

Geodesic leapfrog that is exact for a standard-normal potential. Position and velocity are rotated together in each 2-D plane (q_i, v_i).

Microcanonical

Microcanonical / isokinetic HMC using ESH dynamics (Steeg & Gallagher 2021, ported from the BlackJAX implementation).

The momentum is constrained to the unit sphere (‖v‖ = 1). The momentum update uses the ESH formula which preserves ‖v‖ = 1 exactly while tracking the cumulative kinetic-energy change needed for the Metropolis accept/reject decision.

No partial momentum refreshment is performed — this variant only implements the deterministic ESH trajectory.

Trait Implementations

impl Clone for KineticEnergyKind

fn clone(&self) -> KineticEnergyKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KineticEnergyKind

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

Formats the value using the given formatter.

impl Default for KineticEnergyKind

fn default() -> KineticEnergyKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for KineticEnergyKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for KineticEnergyKind

fn eq(&self, other: &KineticEnergyKind) -> 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 Serialize for KineticEnergyKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
