Struct nyx_space::md::ui::Event

pub struct Event {
    pub parameter: StateParameter,
    pub desired_value: f64,
    pub epoch_precision: TimeUnit,
    pub value_precision: f64,
    pub in_frame: Option<(Frame, Arc<Cosm>)>,
}

Defines a state parameter event finder

Fields

parameter: StateParameter

The state parameter

desired_value: f64

The desired self.desired_value, must be in the same units as the state parameter

epoch_precision: TimeUnit

The time precision after which the solver will report that it cannot find any more precise

value_precision: f64

The precision on the desired value

in_frame: Option<(Frame, Arc<Cosm>)>

An optional frame in which to search this – it IS recommended to convert the whole trajectory instead of searching in a given frame!

Implementations

impl Event

pub fn new(parameter: StateParameter, desired_value: f64) -> Self

Match a specific event for the parameter to hit the specified value. By default, the time precision is 1 millisecond and the value precision is 1e-3 of whatever unit is the default for that parameter. For example, a radius event will seek the requested value at the meter level, and an angle event will seek it at the thousands of a degree.

pub fn within_tolerance(
    parameter: StateParameter,
    desired_value: f64,
    value_precision: f64
) -> Self

Match a specific event for the parameter to hit the specified value with the provided tolerance on the value

pub fn specific(
    parameter: StateParameter,
    desired_value: f64,
    value_precision: f64,
    epoch_precision: TimeUnit
) -> Self

Match a specific event for the parameter to hit the specified value with the provided tolerance on the value and time

pub fn periapsis() -> Self

Match the periapasis i.e. True Anomaly == 0

pub fn apoapsis() -> Self

Match the apoapasis i.e. True Anomaly == 180

pub fn in_frame(
    parameter: StateParameter,
    desired_value: f64,
    target_frame: Frame,
    cosm: Arc<Cosm>
) -> Self

Match a specific event in another frame, using the default epoch precision and value.
