blood_types_s
Instructions
Use the following table to define the methods asked:
Blood Types | Donate Blood to | Receive Blood From |
---|---|---|
A+ | A+, AB+ | A+, A-, O+, O- |
O+ | O+, A+, B+, AB+ | O+, O- |
B+ | B+, AB+ | B+, B-, O+, O- |
AB+ | AB+ | Everyone |
A- | A+, A-, AB+, AB- | A-, O- |
O- | Everyone | O- |
B- | B+, B-, AB+, AB- | B-, O- |
AB- | AB+, AB- | AB-, A-, B-, O- |
Implement three methods for BloodType
:
can_receive_from
: returnstrue
ifself
can receive blood fromother
blood type.donors
: which returns all the blood types that can give blood toself
.recipients
: which returns all the blood types that can receive blood fromself
.
Expected Functions and Structures
#[derive(Debug, PartialEq, Eq, Clone, PartialOrd, Ord)]
pub enum Antigen {
A,
AB,
B,
O,
}
#[derive(Debug, PartialEq, Eq, PartialOrd, Ord, Clone)]
pub enum RhFactor {
Positive,
Negative,
}
#[derive(Debug, PartialEq, Eq, PartialOrd, Ord, Clone)]
pub struct BloodType {
pub antigen: Antigen,
pub rh_factor: RhFactor,
}
impl BloodType {
pub fn can_receive_from(&self, other: &Self) -> bool {
}
pub fn donors(&self) -> Vec<Self> {
}
pub fn recipients(&self) -> Vec<Self> {
}
}
Usage
Here is a program to test your function.
use blood_types_s::{Antigen, BloodType, RhFactor};
fn main() {
let blood_type = BloodType {
antigen: Antigen::O,
rh_factor: RhFactor::Positive,
};
println!("recipients of O+ {:?}", blood_type.recipients());
println!("donors of O+ {:?}", blood_type.donors());
let another_blood_type = BloodType {
antigen: Antigen::O,
rh_factor: RhFactor::Positive,
};
println!(
"donors of O+ can receive from {:?} {:?}",
&another_blood_type,
blood_type.can_receive_from(&another_blood_type)
);
}
And its output
$ cargo run
recipients of O+ [BloodType { antigen: AB, rh_factor: Positive }, BloodType { antigen: O, rh_factor: Positive }, BloodType { antigen: A, rh_factor: Positive }, BloodType { antigen: B, rh_factor: Positive }]
donors of O+ [BloodType { antigen: O, rh_factor: Positive }, BloodType { antigen: O, rh_factor: Negative }]
donors of O+ can receive from BloodType { antigen: O, rh_factor: Positive } true
