Struct SpikeEvent 

pub struct SpikeEvent {
    pub neuron_id: usize,
    pub timestamp: f64,
    pub amplitude: f64,
    pub spatial_coords: Vec<f64>,
}

Neuromorphic spike event

Represents a discrete spike occurring in a neuromorphic system. Each spike carries information about its source, timing, amplitude, and associated spatial coordinates.

Fields

• neuron_id: Unique identifier for the neuron that generated the spike
• timestamp: Time of spike occurrence in simulation time units
• amplitude: Strength/amplitude of the spike
• spatial_coords: Spatial coordinates associated with the spike

Example

use scirs2_spatial::neuromorphic::core::SpikeEvent;

let spike = SpikeEvent {
    neuron_id: 42,
    timestamp: 1000.5,
    amplitude: 1.0,
    spatial_coords: vec![0.5, 0.3, 0.8],
};

println!("Neuron {} spiked at time {}", spike.neuron_id, spike.timestamp);

Fields

neuron_id: usize

Source neuron ID

timestamp: f64

Spike timestamp (in simulation time units)

amplitude: f64

Spike amplitude

spatial_coords: Vec<f64>

Spatial coordinates associated with the spike

Implementations

impl SpikeEvent

pub fn new( neuron_id: usize, timestamp: f64, amplitude: f64, spatial_coords: Vec<f64>, ) -> Self

Get the timestamp of this spike

pub fn amplitude(&self) -> f64

Get the amplitude of this spike

pub fn spatial_coords(&self) -> &[f64]

Get the spatial coordinates associated with this spike

pub fn spatial_dims(&self) -> usize

Get the number of spatial dimensions

pub fn temporal_distance(&self, other: &SpikeEvent) -> f64

Calculate the temporal distance to another spike

Arguments

• other - Another spike event

Returns

Absolute temporal distance between the two spikes

pub fn spatial_distance(&self, other: &SpikeEvent) -> Option<f64>

Calculate the spatial distance to another spike

Arguments

• other - Another spike event

Returns

Euclidean distance between spatial coordinates, or None if dimensions don’t match

pub fn is_before(&self, other: &SpikeEvent) -> bool

Check if this spike occurs before another spike

Arguments

• other - Another spike event

Returns

True if this spike occurs before the other spike

pub fn is_after(&self, other: &SpikeEvent) -> bool

Check if this spike occurs after another spike

Arguments

• other - Another spike event

Returns

True if this spike occurs after the other spike

pub fn same_neuron(&self, other: &SpikeEvent) -> bool

Check if two spikes are from the same neuron

Arguments

• other - Another spike event

Returns

True if both spikes are from the same neuron

Trait Implementations

impl Clone for SpikeEvent

fn clone(&self) -> SpikeEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpikeEvent

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

Formats the value using the given formatter.

impl PartialEq for SpikeEvent

fn eq(&self, other: &Self) -> 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 PartialOrd for SpikeEvent

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
