Struct SequentialSampler 

pub struct SequentialSampler;

A basic, single-threaded sampler.

Trait Implementations

impl Default for SequentialSampler

fn default() -> SequentialSampler

Returns the “default value” for a type.

impl<T: ProbabilisticType> Sampler<T> for SequentialSampler

fn sample( &self, root_node: &ConstTree<UncertainNodeContent>, ) -> Result<SampledValue, UncertainError>

Samples a value from the given root computation node.

This method initiates the sampling process by evaluating the computation graph starting from the root_node. It uses a HashMap for memoization to avoid recomputing values for the same node multiple times within a single sample operation.

Arguments

• root_node - An Arc to the root ComputationNode of the graph to be sampled.

Returns

A Result which is:

• Ok(SampledValue) containing the sampled value if the sampling is successful.
• Err(UncertainError) if an error occurs during sampling (e.g., type mismatch, distribution error).
