Struct EvolutionOptions 

#[non_exhaustive]
pub struct EvolutionOptions {
    pub times: Vec<f64>,
    pub krylov_dimension: usize,
    pub tolerance: f64,
    pub max_substeps: usize,
    pub hamiltonian: bool,
}

Time grid and adaptive Krylov controls for state evolution.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

times: Vec<f64>

Finite nondecreasing output times measured from the initial state.

krylov_dimension: usize

Maximum dimension of each Krylov projection.

tolerance: f64

Local error tolerance.

max_substeps: usize

Maximum accepted and rejected trial intervals.

hamiltonian: bool

Interpret the generator as H and apply exp(-i H t) when true.

Implementations

impl EvolutionOptions

pub fn new(times: impl Into<Vec<f64>>) -> Self

Construct Hamiltonian evolution controls on the supplied output grid.

pub fn with_krylov_dimension(self, dimension: usize) -> Self

Set the maximum dimension of each Krylov projection.

pub fn with_tolerance(self, tolerance: f64) -> Self

Set the local error tolerance.

pub fn with_max_substeps(self, max_substeps: usize) -> Self

Set the maximum accepted and rejected trial intervals.

pub fn with_hamiltonian(self, hamiltonian: bool) -> Self

Select Hamiltonian (exp(-iHt)) or direct-generator evolution.

Trait Implementations

impl Clone for EvolutionOptions

fn clone(&self) -> EvolutionOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvolutionOptions

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

Formats the value using the given formatter.

impl PartialEq for EvolutionOptions

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