Enum SampleInvariant 

pub enum SampleInvariant {
    StimulusLenMismatch {
        expected: usize,
        got: usize,
    },
    NonFiniteStimulus {
        channel: usize,
    },
    InfiniteReward,
}

Batch-admission invariant violated by one TrainingExample.

Produced by PlasticityTrainer::run_session’s preflight pass before any network, modulator, eligibility, or metric state mutates. Single-step APIs (train_step, train_step_with_modulators, and train_step_from_critic) do not run this check — they stay compatible with their existing StepError contracts, including NaN-reward skipping in train_step.

TrainingExample has no sample IDs, so ordering is the batch slice order (index 0 is the first example). TrainingConfig currently has no invalid encodings (use_reward_modulation is a bool); there is therefore no config-level rejection variant.

Variants

StimulusLenMismatch

stimuli.len() did not match SpikingNetwork::num_channels.

Fields

expected: usize

got: usize

NonFiniteStimulus

A stimulus component was NaN or ±infinity.

Fields

channel: usize

InfiniteReward

Reward was ±infinity (NaN remains allowed: train_step skips modulation and run_session omits it from avg_reward).
