Struct RepeatedDelayPattern 

pub struct RepeatedDelayPattern {
    pub pattern: Vec<Box<dyn DelayTraceConfig>>,
    pub count: usize,
    /* private fields */
}

The model contains an array of delay trace models.

Combine multiple delay trace models into one delay pattern, and repeat the pattern for count times.

If count is 0, the pattern will be repeated forever.

Examples

The most common use case is to read from a configuration file and deserialize it into a RepeatedDelayPatternConfig:

// The content would be "{\"RepeatedDelayPatternConfig\":{\"pattern\":[{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":10000000},\"duration\":{\"secs\":1,\"nanos\":0}}},{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":20000000},\"duration\":{\"secs\":1,\"nanos\":0}}}],\"count\":2}}"
// if the `human` feature is not enabled.
let config_file_content = "{\"RepeatedDelayPatternConfig\":{\"pattern\":[{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":10000000},\"duration\":{\"secs\":1,\"nanos\":0}}},{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":20000000},\"duration\":{\"secs\":1,\"nanos\":0}}}],\"count\":2}}";
let des: Box<dyn DelayTraceConfig> = serde_json::from_str(config_file_content).unwrap();
let mut model = des.into_model();
assert_eq!(
    model.next_delay(),
    Some((Delay::from_millis(10), Duration::from_secs(1)))
);
assert_eq!(
    model.next_delay(),
    Some((Delay::from_millis(20), Duration::from_secs(1)))
);
assert_eq!(
    model.next_delay(),
    Some((Delay::from_millis(10), Duration::from_secs(1)))
);
assert_eq!(
    model.next_delay(),
    Some((Delay::from_millis(20), Duration::from_secs(1)))
);
assert_eq!(model.next_delay(), None);

You can also build manually:

let pat = vec![
    Box::new(
        StaticDelayConfig::new()
            .delay(Delay::from_millis(10))
            .duration(Duration::from_secs(1)),
    ) as Box<dyn DelayTraceConfig>,
    Box::new(
        StaticDelayConfig::new()
            .delay(Delay::from_millis(20))
            .duration(Duration::from_secs(1)),
    ) as Box<dyn DelayTraceConfig>,
];
let ser = Box::new(RepeatedDelayPatternConfig::new().pattern(pat).count(2)) as Box<dyn DelayTraceConfig>;
let ser_str = serde_json::to_string(&ser).unwrap();
// The json string would be "{\"RepeatedDelayPatternConfig\":{\"pattern\":[{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":10000000},\"duration\":{\"secs\":1,\"nanos\":0}}},{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":20000000},\"duration\":{\"secs\":1,\"nanos\":0}}}],\"count\":2}}"
// if the `human` feature is not enabled.
let json_str = "{\"RepeatedDelayPatternConfig\":{\"pattern\":[{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":10000000},\"duration\":{\"secs\":1,\"nanos\":0}}},{\"StaticDelayConfig\":{\"delay\":{\"secs\":0,\"nanos\":20000000},\"duration\":{\"secs\":1,\"nanos\":0}}}],\"count\":2}}";
assert_eq!(ser_str, json_str);
