Struct KindFilter 

pub struct KindFilter { /* private fields */ }

Filters adapters by their kind (pure matcher, no include/exclude semantics).

This filter matches adapters whose kind is contained in the specified set. Use with FilterChain to apply include/exclude logic.

Examples

use ddns_a::network::filter::{KindFilter, AdapterFilter};
use ddns_a::network::{AdapterSnapshot, AdapterKind};

// Match wireless and ethernet adapters
let filter = KindFilter::new([AdapterKind::Wireless, AdapterKind::Ethernet]);

let eth = AdapterSnapshot::new("eth0", AdapterKind::Ethernet, vec![], vec![]);
let loopback = AdapterSnapshot::new("lo", AdapterKind::Loopback, vec![], vec![]);

assert!(filter.matches(&eth));
assert!(!filter.matches(&loopback));

Implementations

impl KindFilter

pub fn new(kinds: impl IntoIterator<Item = AdapterKind>) -> Self

Creates a kind filter matching any of the specified kinds.

pub fn is_empty(&self) -> bool

Returns true if no kinds are configured (matches nothing).

pub fn len(&self) -> usize

Returns the number of kinds in the filter.

pub fn kinds(&self) -> &HashSet<AdapterKind>

Returns a reference to the set of kinds.

Trait Implementations

impl AdapterFilter for KindFilter

fn matches(&self, adapter: &AdapterSnapshot) -> bool

Returns true if the adapter should be included, false to filter it out.

impl Clone for KindFilter

fn clone(&self) -> KindFilter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KindFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
