Struct CosmoBuilder 

pub struct CosmoBuilder { /* private fields */ }

Implementations

impl CosmoBuilder

pub fn new() -> Self

Create a new builder with default accuracy settings.

pub fn flat(self) -> Self

Enforce spatial flatness (Ω_k = 0) and solve for ω_Λ by closure.

pub fn h(self, val: f64) -> Self

Set the dimensionless Hubble parameter h (H0 = 100 h).

pub fn H0(self, val: f64) -> Self

Set H0 in (km/s)/Mpc (converted internally to h).

pub fn Omega_m(self, val: f64) -> Self

Set total matter density Ω_m.

pub fn Omega_b(self, val: f64) -> Self

Set baryon density Ω_b.

pub fn Omega_cdm(self, val: f64) -> Self

Set CDM density Ω_cdm.

pub fn Omega_k(self, val: f64) -> Self

Set curvature density Ω_k.

pub fn Omega_L(self, val: f64) -> Self

Set dark energy density Ω_Λ.

pub fn omega_b_phys(self, val: f64) -> Self

Set physical baryon density ω_b.

pub fn omega_cdm_phys(self, val: f64) -> Self

Set physical CDM density ω_cdm.

pub fn T_cmb0(self, val: f64) -> Self

Set the present-day CMB temperature T_cmb0 in Kelvin.

pub fn accuracy(self, val: AccuracyPreset) -> Self

Set the global accuracy preset controlling numerical settings.

pub fn neutrino_effective(self, n_eff: f64, masses_ev: Vec<f64>) -> Self

Use an “effective” neutrino model with total n_eff and a mass list.

For massless neutrinos, pass [0.0] (or multiple zeros if you want explicit states).

pub fn neutrino_split( self, n_ur: f64, masses_ev: Vec<f64>, temp_factors: Vec<f64>, ) -> Self

Use a “split” neutrino model with explicit ultra-relativistic contribution n_ur plus a list of massive eigenstates and per-species temperature factors.

pub fn build(self) -> Result<ScientificParams, String>

Build ScientificParams by resolving inputs, enforcing consistency, and computing all derived quantities.
