Struct ErmentroutKopellMapNeuron 

pub struct ErmentroutKopellMapNeuron {
    pub theta: f64,
    pub dt: f64,
    pub gain: f64,
    pub theta_threshold: f64,
}

Ermentrout-Kopell canonical Type I — theta neuron in map form.

The canonical model for Type I (saddle-node) excitability. theta(n+1) = theta(n) + dt * [(1 - cos(theta)) + (1 + cos(theta)) * gain * I] Spike when theta crosses pi.

Implementations

impl ErmentroutKopellMapNeuron

pub fn new() -> Self

fn parameters_are_valid(&self) -> bool

pub fn try_step(&mut self, current: f64) -> Result<i32, &'static str>

Checked update. Rejected input or candidates leave phase unchanged.

pub fn step(&mut self, current: f64) -> i32

Infallible NetworkRunner adapter; invalid updates are event-silent and atomic.

pub fn simulate( &mut self, n_steps: usize, current: f64, ) -> Result<(Vec<f64>, i64), &'static str>

Run n_steps under a constant input, returning the theta trace (wrapped to [0, 2*pi)) and the upward-crossing spike count. Reuses step so the trace matches the per-step path; on a shared libm it also matches the Python reference bit-for-bit (the only transcendental is cos, and the non-chaotic phase flow does not amplify ULP differences). The final state is left in self.theta.

pub fn reset(&mut self)
