Struct RoleHierarchyTree

pub struct RoleHierarchyTree {
    pub root: RoleNode,
    pub total_roles: usize,
    pub max_depth: usize,
    pub metadata: HierarchyMetadata,
}

Represents a complete role hierarchy tree structure.

This type provides a structured view of role relationships that can be used for visualization, API responses, or external system integration.

Example

let storage = MemoryStorage::new();
let role_sys = RoleSystem::with_storage(storage, RoleSystemConfig::default());
let role_system = AsyncRoleSystem::new(role_sys);

// Get hierarchy tree from role system
let tree = role_system.get_hierarchy_tree(None).await?;
println!("Total roles: {}, Max depth: {}", tree.total_roles, tree.max_depth);

Fields

root: RoleNode

Root node of the hierarchy tree

total_roles: usize

Total number of roles in the tree

max_depth: usize

Maximum depth of the hierarchy

metadata: HierarchyMetadata

Metadata about the tree structure
