        parent_a: Arc<ParentSnapshot>,

}

Lineage of a chromosome: how it was derived from seeds.

Variants

Genesis

Original randomly-generated chromosome.

Fields

generation: u32

Generation when created.

Crossover

Created via crossover of two parents.

Fields

parent_a: Arc<ParentSnapshot>

Parent A snapshot — genes only, breaks ancestry chain.

parent_b: Arc<ParentSnapshot>

Parent B snapshot — genes only, breaks ancestry chain.

strategy: String

Strategy used.

generation: u32

Generation when created.

Mutation

Created via mutation of a single parent.

Fields

parent: Arc<ParentSnapshot>

Parent snapshot — genes only, breaks ancestry chain.

log: Vec<MutationOp>

Log of applied mutation operations.

generation: u32

Generation when created.

Implementations

impl Lineage

pub fn genesis(generation: u32) -> Self

Create a genesis lineage.

pub fn crossover( parent_a: &Chromosome, parent_b: &Chromosome, strategy: &str, generation: u32, ) -> Self

Create a crossover lineage.

pub fn mutation( parent: &Chromosome, log: Vec<MutationOp>, generation: u32, ) -> Self

Create a mutation lineage.

pub fn to_trace(&self) -> String

Serialize lineage to a compact string representation.

Trait Implementations

impl Clone for Lineage

fn clone(&self) -> Lineage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Lineage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Lineage

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Lineage

fn eq(&self, other: &Lineage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Lineage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
