pub struct Proportion(_);
Expand description

An ancestry proportion.

This is a newtype wrapper for f64.

Interpretation

With respect to a deme in an offspring time step, a proportion is the fraction of ancsestry from a given parental deme.

Examples

In YAML input

Ancestral proportions of demes

let yaml = "
time_units: generations
description:
  An admixed deme appears 100 generations ago.
  Its initial ancestry is 90% from ancestor1
  and 10% from ancestor2.
demes:
 - name: ancestor1
   epochs:
    - start_size: 50
      end_time: 100
 - name: ancestor2
   epochs:
    - start_size: 50
      end_time: 100
 - name: admixed
   ancestors: [ancestor1, ancestor2]
   proportions: [0.9, 0.1]
   start_time: 100
   epochs:
    - start_size: 200
";
demes::loads(yaml).unwrap();

Pulse proportions

let yaml = "
time_units: generations
description:
   Two demes coexist without migration.
   Sixty three (63) generations ago,
   deme1 contributes 50% of ancestry
   to all individuals born in deme2.
demes:
 - name: deme1
   epochs:
    - start_size: 50
 - name: deme2
   epochs:
    - start_size: 50
pulses:
 - sources: [deme1]
   dest: deme2
   proportions: [0.5]
   time: 63
";
demes::loads(yaml).unwrap();

Using rust code

Normally, one only needs to create a Proportion when working with GraphBuilder.

let t = demes::Proportion::from(0.5);
assert_eq!(t, 0.5);
