Struct Replay 

pub struct Replay { /* private fields */ }

A fake sensor that replays a fixed sequence of readings.

Where a SimSensor generates a signal, a Replay plays back exact values in order, which is what a deterministic test or a scripted demo wants: spell out the readings that tell the story, and the sensor yields them one per read. A one-shot replay reports [Error::Closed] once the sequence is exhausted; a repeating one loops forever.

Examples

use pamoja_core::Sensor;
use pamoja_sim::Replay;

let mut gauge = Replay::new(vec![1.0, 1.2, 1.9]);
assert_eq!(gauge.read().await?, 1.0);
assert_eq!(gauge.read().await?, 1.2);

Implementations

impl Replay

pub fn new(readings: Vec<f32>) -> Self

Creates a sensor that yields readings once, then reports closed.

Arguments

• readings - the values to play back in order.

Returns

A one-shot replay sensor.

pub fn repeating(readings: Vec<f32>) -> Self

Creates a sensor that yields readings in a loop forever.

Arguments

• readings - the values to play back in order, repeating from the start.

Returns

A repeating replay sensor.

Trait Implementations

impl Clone for Replay

fn clone(&self) -> Replay

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Replay

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

Formats the value using the given formatter.

impl Sensor for Replay

type Reading = f32

The value produced by a single read, for example a temperature or a fix.

async fn read(&mut self) -> Result<f32>

Takes a single reading from the sensor.
