Struct emcee::Step

pub struct Step<'a> {
    pub pos: Cow<'a, [Guess]>,
    pub lnprob: Cow<'a, [f64]>,
    pub iteration: usize,
}

Struct representing the current iteration evaluation

This struct is used with sample, which supplies a callback to each loop step. An instance of this struct is passed to the callback.

Technical note: the pos and lnprob slices are implemented as Cow wrapped objects, as during iteration, their contents are references (as the values are stored with a longer lived lifetime in the sampler method), whereas the function must return owned values.

Fields

pos: Cow<'a, [Guess]>

The current list of parameters, one for each walker

lnprob: Cow<'a, [f64]>

The log posterior probabilities of the values contained in pos, one for each walker

iteration: usize

The current iteration number
