Struct cassowary::Variable

pub struct Variable(_);

Identifies a variable for the constraint solver. Each new variable is unique in the view of the solver, but copying or cloning the variable produces a copy of the same variable.

Methods

impl Variable

pub fn new() -> Variable

Produces a new unique variable for use in constraint solving.
