Enum Trigger 

#[non_exhaustive]
pub enum Trigger {
    Apogee,
    Altitude {
        height_above_ground_m: f64,
    },
    Time {
        time_s: f64,
    },
    MotorDelay {
        motor: usize,
    },
    Burnout {
        motor: usize,

    },
}

When a device’s charge fires.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Apogee

At apogee.

Altitude

The first time from apogee that the center of mass is at or below this height above the launch site, m: an altimeter’s main setting. A rocket whose apogee is already below it fires at apogee.

Fields

height_above_ground_m: f64

The height above the launch site, m.

Time

At a time after launch, s. Charges are checked in free flight and during the descent, so a time that passes on the pad or the rail fires at rail exit.

Fields

time_s: f64

The time after launch, s.

MotorDelay

A motor’s ejection delay after that motor’s burnout. The motor is its index in hpr_design::Assembly::motors, and it must have a hpr_motor::Delay::Seconds delay. As Self::Time, a delay that expires before the rail exit fires there. A motor that never lights never fires it, so on a cluster with a motor out (hpr_design::MountedMotor::failed_tubes) name a tube that lights.

Fields

motor: usize

The motor’s index.

Burnout

A delay after a motor’s burnout, whatever its ejection delay: a stage separation timed from the booster’s burnout. The motor is its index in hpr_design::Assembly::motors. As Self::MotorDelay, it fires no earlier than the rail exit, and never if the motor never lights.

Fields

motor: usize

The motor’s index.

delay_s: f64

The delay after its burnout, s.

Implementations

impl Trigger

pub fn known_time_s(self, assembly: &Assembly) -> Result<Option<f64>, SimError>

When it fires on a flight of assembly, if that is known before the flight: a Self::Time, or a delay after the burnout of a motor assembly lights at a known time (one lit by a separation has none yet). None for Self::Apogee and Self::Altitude, which the flight watches for. A time that passes on the pad or the rail fires at the rail exit in flight, which this does not know.

Errors

SimError::Domain as the flight refuses the trigger: a time before launch, a motor that isn’t there, a Self::MotorDelay on a motor with no ejection delay in seconds, or a delay that is negative or not finite.

Trait Implementations

impl Clone for Trigger

fn clone(&self) -> Trigger

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Trigger

impl Debug for Trigger

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Trigger

fn deserialize<__D>( __deserializer: __D, ) -> Result<Trigger, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Trigger

fn eq(&self, other: &Trigger) -> 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 Serialize for Trigger

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
