Trait Preference 

pub trait Preference {
    // Required method
    fn evaluate(&self, reader: &Reader<'_>) -> GeopResult<Constraint>;
}

What a solve should prefer among the states where the constraints hold: residuals it wants small — not zero at any price — where the part is as reader reads it, each a length, and their derivatives by the state. A drag, pulling a point of a placed part towards the pointer.

Required Methods

fn evaluate(&self, reader: &Reader<'_>) -> GeopResult<Constraint>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
