Struct EnabledServices 

pub struct EnabledServices { /* private fields */ }

Set of enabled services in a topology

Provides information about which services are enabled in the topology. This is needed because network assignments depend on inter-service relationships (e.g., Tracker needs Metrics network only if Prometheus exists).

Design

Uses a HashSet<Service> internally, following the Open/Closed principle: adding new services doesn’t require adding new fields or methods.

Examples

use torrust_tracker_deployer_lib::domain::topology::{EnabledServices, Service};

// Create with specific services enabled
let enabled = EnabledServices::from(&[Service::Prometheus, Service::Grafana]);

assert!(enabled.has(Service::Prometheus));
assert!(enabled.has(Service::Grafana));
assert!(!enabled.has(Service::Caddy));
assert!(!enabled.has(Service::MySQL));

Implementations

impl EnabledServices

pub fn from(services: &[Service]) -> Self

Creates a new set of enabled services from a slice

This is the primary constructor. The services slice represents which optional services are present in the deployment.

Examples

use torrust_tracker_deployer_lib::domain::topology::{EnabledServices, Service};

let enabled = EnabledServices::from(&[Service::Prometheus, Service::MySQL]);

assert!(enabled.has(Service::Prometheus));
assert!(enabled.has(Service::MySQL));

pub fn has(&self, service: Service) -> bool

Checks if a specific service is enabled

Examples

use torrust_tracker_deployer_lib::domain::topology::{EnabledServices, Service};

let enabled = EnabledServices::from(&[Service::Caddy]);

assert!(enabled.has(Service::Caddy));
assert!(!enabled.has(Service::MySQL));
