Enum fj_kernel::partial::MaybePartial

pub enum MaybePartial<T: HasPartial> {
    Full(T),
    Partial(T::Partial),
}

Can be used everywhere either a partial or full objects are accepted

Some convenience methods are available for specific instances of MaybePartial (like, MaybePartial<Curve>, or MaybePartial<Vertex>).

Implementation Note

The set of available convenience methods is far from complete. Please feel free to just add more, if you need them.

Variants

Full(T)

A full object

Partial(T::Partial)

A partial object

Implementations

impl<T: HasPartial> MaybePartial<T>

pub fn update_partial(self, f: impl FnOnce(T::Partial) -> T::Partial) -> Self

If this is a partial object, update it

This is useful whenever a partial object can infer something about its parts from other parts, and wants to update what was inferred, in case it can be updated.

pub fn into_full(self, stores: &Stores) -> T

Return or build a full object

If this already is a full object, it is returned. If this is a partial object, the full object is built from it, using Partial::build.

pub fn into_partial(self) -> T::Partial

Return or convert a partial object

If this already is a partial object, is is returned. If this is a full object, it is converted into a partial object using HasPartial::to_partial.

impl MaybePartial<Curve>

pub fn global_form(&self) -> Option<Handle<GlobalCurve>>

Access the global form

impl MaybePartial<GlobalEdge>

pub fn curve(&self) -> Option<&Handle<GlobalCurve>>

Access the curve

impl MaybePartial<SurfaceVertex>

pub fn position(&self) -> Option<Point<2>>

Access the position

pub fn surface(&self) -> Option<&Handle<Surface>>

Access the surface

impl MaybePartial<Vertex>

pub fn surface_form(&self) -> Option<MaybePartial<SurfaceVertex>>

Access the surface form
