Enum Variation 

pub enum Variation {
    Fixed,
    Seeded(u64),
    RoundRobin,
    Random,
}

Controls how template alternatives are selected.

Fixed and RoundRobin are literal: they honour the contract exactly (first alternative every time / strict rotation in registration order). Seeded and Random additionally layer discourse-aware choose-best scoring on top, so candidates that repeat recent words or flatten recent sentence cadence are penalised.

Variants

Fixed

Always pick the first registered template, every render.

Seeded(u64)

Deterministic hash-based selection. Same seed + key = same index. Further refined by discourse-aware choose-best scoring.

RoundRobin

Cycle through alternatives in registration order, strictly.

Random

Select randomly (non-deterministic). Layered with choose-best scoring.

Trait Implementations

impl Clone for Variation

fn clone(&self) -> Variation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Variation

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

Formats the value using the given formatter.

impl Default for Variation

fn default() -> Variation

Returns the “default value” for a type.

impl PartialEq for Variation

fn eq(&self, other: &Variation) -> 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 Copy for Variation

impl Eq for Variation

impl StructuralPartialEq for Variation
