Trait Params 

pub trait Params:
    Send
    + Sync
    + Clone {
    // Required methods
    fn dimension(&self) -> usize;
    fn values(&self) -> impl Iterator<Item = &f64>;
    fn collect(iter: impl Iterator<Item = f64>) -> Self;
}

Model parameters defining the state space of the Markov chain

Required Methods

fn dimension(&self) -> usize

Dimension of the state space

This can depend on self in situations where the number of parameters depends on the data itself, e.g. the number of groups in a hierarchical model.

fn values(&self) -> impl Iterator<Item = &f64>

Access the individual parameter values as an iterator

fn collect(iter: impl Iterator<Item = f64>) -> Self

Collect new parameters from the given iterator

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
