Struct CompositeGenome 

pub struct CompositeGenome<A, B>
where
    A: EvolutionaryGenome,
    B: EvolutionaryGenome,
{
    pub first: A,
    pub second: B,
}

A composite genome combining two different genome types

This is useful for problems that require multiple representations, such as:

• Continuous parameters + discrete choices
• Feature selection (binary) + feature weights (continuous)
• Topology (permutation) + parameters (continuous)

Type Parameters

• A: The first genome type
• B: The second genome type

Fields

first: A

First component genome

second: B

Second component genome

fn to_trace(&self) -> Trace

Convert composite genome to Fugue trace.

Each component is delegated to its own to_trace, and every entry of the resulting nested trace is copied verbatim under a namespace prefix ("first/" / "second/"). This preserves full fidelity for any component genome type — including Permutation, TreeGenome and future encodings — rather than special-casing a fixed set of address name literals.

fn from_trace(trace: &Trace) -> Result<Self, GenomeError>

Reconstruct composite genome from Fugue trace.

Strips the "first/" / "second/" namespace back off each entry to rebuild the two component sub-traces, then delegates to each component’s own from_trace.

fn trace_prefix() -> &'static str

Get the address prefix used for trace storage (default: "gene").
