Enum Part 

#[non_exhaustive]
pub enum Part {
    NoseCone(NoseCone),

    Parachute(Parachute),
    Streamer(Streamer),
    ShockCord(ShockCord),
}

A part in the tree. Serialized as an object with one key, the part’s kind.

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.

NoseCone(NoseCone)

A nose cone (body component).

BodyTube(BodyTube)

A body tube (body component).

Transition(Transition)

A transition (body component).

InnerTube(InnerTube)

An inner tube (internal): a coupler, motor mount tube or engine block.

CenteringRing(CenteringRing)

A centering ring or bulkhead (internal).

FinSet(FinSet)

A fin set (external, on a body tube). Its axial extent is the root chord.

TubeFinSet(TubeFinSet)

Tube fins (external, on a body tube).

LaunchLug(LaunchLug)

Launch lugs (external, on a body tube). The extent covers the whole row.

RailButton(RailButton)

Rail buttons (external, on a body tube). The extent covers the whole row.

PodSet(PodSet)

Pods (external, on a body tube). Its children are the pod’s body components, which stack along the pod’s axis; its extent is theirs (Component::length_m).

MassComponent(MassComponent)

A mass component (internal).

Parachute(Parachute)

A parachute (internal).

Streamer(Streamer)

A streamer (internal).

ShockCord(ShockCord)

A shock cord (internal).

Implementations

impl Part

pub fn kind_name(&self) -> &'static str

The part’s kind, as serialized.

pub fn is_body(&self) -> bool

Whether this is a body component: a nose cone, body tube or transition.

pub fn is_external(&self) -> bool

Whether this attaches to the outside of a body tube: fins, tube fins, lugs, rail buttons, pods.

pub fn length_m(&self) -> f64

The axial extent used to place the part, m: a body component’s length without shoulders, a fin set’s root chord, a row of lugs or buttons from the first one’s forward end to the last one’s aft end, and a packed part’s packed length. A pod set’s extent is its pods’ body components, which the part alone doesn’t hold, so here it is 0: see Component::length_m.

pub fn packing(&self) -> Option<&Packing>

How a mass object or recovery part is packed, or None for a part that is not packed.

pub fn fore_radius_m(&self) -> Option<f64>

A body component’s outer radius at its forward end, m (zero at a nose tip).

pub fn aft_radius_m(&self) -> Option<f64>

A body component’s outer radius at its aft end, m.

pub fn max_radius_m(&self) -> Result<Option<f64>, DesignError>

A body component’s largest outer radius anywhere along it, m.

Errors

Profile errors for a nose cone or transition.

pub fn inner_radius_m(&self) -> Option<f64>

The inside radius of a body tube or inner tube, m: where internal parts fit.

pub fn axis_offset_m(&self) -> [f64; 2]

Where the part’s own axis crosses the x–y plane, [x, y] in body axes, m: an inner tube’s or packed part’s radial offset turned by its angle, and the body axis for every other part.

pub fn outer_radius_about_axis_m(&self) -> Option<f64>

An internal part’s outer radius about its own axis, m: an inner tube’s or ring’s outer radius, or a packed part’s packed radius.

pub fn reach_from_m(&self, axis: [f64; 2]) -> Option<f64>

How far an internal part reaches from axis ([x, y] in body axes, m): the distance between the two axes plus the part’s outer radius, for the farthest tube of a cluster.

pub fn mass_properties( &self, body_radius_m: Option<f64>, ) -> Result<MassProperties, DesignError>

Mass properties in the part’s own frame. External attachments need the radius of the body they sit on.

Errors

The part’s own geometry, material and numerical errors, and DesignError::Geometry when an external attachment has no body radius.

Trait Implementations

impl Clone for Part

fn clone(&self) -> Part

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Part

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Part

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Part

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Part

fn eq(&self, other: &Part) -> 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 Part

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Part
