Struct HostsView 

pub struct HostsView<'a> { /* private fields */ }

A view over the hosts collection in an inventory that applies transform functions on access.

This struct provides a read-only view of the hosts stored in an Inventory. When accessing individual hosts through this view, any configured transform function is automatically applied. The view caches transformed results to improve performance on subsequent accesses to the same host.

The view does not own the inventory data; it holds a reference to the parent Inventory and provides methods to iterate over hosts, look up hosts by name, and query collection metadata.

Lifetime

• 'a - The lifetime of the reference to the parent Inventory. The view cannot outlive the inventory it references.

Examples

let mut hosts = Hosts::new();
hosts.add_host("router1", Host::builder().hostname("10.0.0.1").build());
let inventory = Inventory::builder().hosts(hosts).build();

let hosts_view = inventory.hosts();
assert_eq!(hosts_view.len(), 1);

if let Some(host) = hosts_view.get("router1") {
    assert_eq!(host.hostname(), Some("10.0.0.1"));
}

for (name, host) in hosts_view.iter() {
    println!("Host: {}", name);
}
