Struct DebouncePolicy

pub struct DebouncePolicy { /* private fields */ }

Expand description

Policy for debouncing IP change events.

Debouncing merges changes that occur within a time window, avoiding rapid consecutive triggers (flapping) from causing duplicate notifications.

§Merge Semantics

Scenario	Event Sequence in Window	Output	Reason
Flicker	`Added(IP) → Removed(IP)`	Empty	Same IP add/remove cancel out
Reverse Flicker	`Removed(IP) → Added(IP)`	Empty	Same IP remove/add cancel out
Replacement	`Removed(old) → Added(new)`	Both events	Different IPs, independent
Duplicate Add	`Added(IP) → Added(IP)`	One Added	Idempotent merge

§Implementation

At window end, compute net change for each (adapter, address):

Net > 0: Output Added
Net < 0: Output Removed
Net = 0: No output (cancelled out)

Implementations§

impl DebouncePolicy

pub const fn new(window: Duration) -> Self

Creates a new debounce policy with the specified window duration.

pub const fn window(&self) -> Duration

Returns the debounce window duration.

Trait Implementations§

impl Clone for DebouncePolicy

fn clone(&self) -> DebouncePolicy

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for DebouncePolicy

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

Formats the value using the given formatter. Read more

impl Default for DebouncePolicy

fn default() -> Self

Creates a default debounce policy with a 2-second window.

The 2-second default balances responsiveness with protection against rapid changes during network configuration updates.

impl PartialEq for DebouncePolicy

fn eq(&self, other: &DebouncePolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
