Enum SeedPurpose 

#[repr(u8)]
pub enum SeedPurpose {
    Init = 0,
    Selection = 1,
    Crossover = 2,
    Mutation = 3,
    Replacement = 4,
    Trial = 5,
    Other = 6,
}

Tag identifying which evolutionary operation a sub-stream is for.

Mixing the purpose into the seed means that, within a single generation, selection and mutation draw from non-overlapping PRNG streams — critical for reproducing trial-level determinism across refactors that reorder operator calls.

Variants

Init = 0

Initial population sampling.

Selection = 1

Parent selection.

Crossover = 2

Recombination / crossover.

Mutation = 3

Mutation.

Replacement = 4

Replacement / survivor selection.

Trial = 5

Differential-evolution trial-vector construction.

Other = 6

Catch-all for strategy-specific stochastic steps.

Trait Implementations

impl Clone for SeedPurpose

fn clone(&self) -> SeedPurpose

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SeedPurpose

impl Debug for SeedPurpose

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

Formats the value using the given formatter.

impl Eq for SeedPurpose

impl Hash for SeedPurpose

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SeedPurpose

fn eq(&self, other: &SeedPurpose) -> 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.
