Struct Body 

pub struct Body<'a> {
    pub name: String,
    pub free: bool,
    pub carrier: Option<usize>,
    pub world: Pose,
    pub part: Reader<'a>,
    pub file: String,
}

A rigid body of the mechanism: a part placed in the assembly, however deep.

Fields

name: String

Its name in the assembly: hinge/pin.

free: bool

Whether the mates may move it: it has a pose of its own to solve for, and no fixed mate holds it.

carrier: Option<usize>

The body it is carried by, by index: for a copy of a pattern, the part it copies — it goes where the pattern puts it after that part, and moves with it as one.

world: Pose

Where it is in the assembly.

part: Reader<'a>

Its part, as placed.

file: String

The file its part is placed from.
