Neuromorphic computing in pure Rust, the open corpus in one library, every module checked against a closed form and audited by mutation: spiking neurons from Hodgkin-Huxley to resonate-and-fire, synapses, STDP to three-factor and dendritic learning, surrogate gradients, BPTT, e-prop, ANN-to-SNN conversion, spiking convolutions and attention, reservoirs, the NEF, vector symbolic architectures, sparse coding, associative memories, QUBO by stochastic spiking, oscillators, ring attractors and neural fields, predictive coding, equilibrium propagation, a cerebellum, grid cells, learnable delays, stochastic resonance, spike-train metrics, graph algorithms by spike wavefront, cochlea, olfaction, touch, proprioception, sound localisation, event vision and fusion, hardware constraint models, NIR, AEDAT/EVT3/N-MNIST decoders, NeuroBench metrics, and a joules ledger that charges for synapse memory traffic. Zero dependencies, std-only, wasm-clean, deterministic by seed.
