Trait schema_analysis::traits::Coalesce[−][src]

pub trait Coalesce {
    fn coalesce(&mut self, other: Self)
    where
        Self: Sized;
}
Expand description

This trait defines a way to merge two instances of the same type.

let mut context_1: BooleanContext = Default::default();
context_1.aggregate(&true);
context_1.aggregate(&true);
let mut schema_1 = Schema::Boolean(context_1);

let mut context_2: BooleanContext = Default::default();
context_2.aggregate(&false);
let mut schema_2 = Schema::Boolean(context_2);

schema_1.coalesce(schema_2); // schema_2 is gone.

let mut context_merged: BooleanContext = Default::default();
context_merged.aggregate(&true);
context_merged.aggregate(&true);
context_merged.aggregate(&false);
let schema_merged = Schema::Boolean(context_merged);

assert_eq!(schema_1, schema_merged);

Required methods

Merge other into self.
