Struct RoleCatalog 

pub struct RoleCatalog {
    roles: HashMap<RoleId, RoleSpec>,
}

Immutable map of RoleId → RoleSpec for the built-in specialist roles.

Construct via RoleCatalog::default(); the seven built-in roles are always present. YAML-overridable catalogs are deferred to a future phase.

Example

use gglib_core::domain::council::role_catalog::{RoleCatalog, RoleId};

let catalog = RoleCatalog::default();
assert_eq!(catalog.len(), 7);
assert!(catalog.get(&RoleId::new("researcher")).is_some());
assert!(catalog.get(&RoleId::new("unknown-role")).is_none());

Fields

roles: HashMap<RoleId, RoleSpec>

Implementations

impl RoleCatalog

pub fn get(&self, id: &RoleId) -> Option<&RoleSpec>

Look up a role by id.

Returns None if no role with the given id exists in the catalog.

Example

use gglib_core::domain::council::role_catalog::{RoleCatalog, RoleId};

let catalog = RoleCatalog::default();
let spec = catalog.get(&RoleId::new("writer")).unwrap();
assert_eq!(spec.display_name, "Writer");
assert!(catalog.get(&RoleId::new("nonexistent")).is_none());

pub fn len(&self) -> usize

Return the number of roles in the catalog.

Example

use gglib_core::domain::council::role_catalog::RoleCatalog;

let catalog = RoleCatalog::default();
assert_eq!(catalog.len(), 7);

pub fn is_empty(&self) -> bool

Return true if the catalog contains no roles.

pub fn iter(&self) -> impl Iterator<Item = (&RoleId, &RoleSpec)>

Return an iterator over (RoleId, RoleSpec) pairs.
