Struct PathManager 

pub struct PathManager { /* private fields */ }

Manager for tracking and closing redundant paths

Manages open paths and closes redundant ones when a best path is selected. Rules:

1. Never close relay paths (they’re fallback)
2. Keep at least MIN_DIRECT_PATHS direct paths open
3. Never close the selected path

Implementations

impl PathManager

pub fn new() -> Self

Create a new path manager

pub fn with_min_direct_paths(min_direct_paths: usize) -> Self

Create a path manager with custom minimum direct paths

pub fn add_path(&mut self, info: PathInfo)

Add a path to track

pub fn remove_path(&mut self, addr: &SocketAddr)

Remove a path

pub fn set_selected_path(&mut self, addr: SocketAddr)

Set the selected (best) path

pub fn selected_path(&self) -> Option<SocketAddr>

Get the selected path

pub fn contains(&self, addr: &SocketAddr) -> bool

Check if a path is tracked

pub fn is_relay_path(&self, addr: &SocketAddr) -> bool

Check if a path is a relay path

pub fn direct_path_count(&self) -> usize

Count of open direct paths

pub fn relay_path_count(&self) -> usize

Count of open relay paths

pub fn open_paths(&self) -> Vec<&PathInfo>

Get all open paths

pub fn close_redundant_paths(&mut self) -> Vec<SocketAddr>

Close redundant paths, returning list of closed addresses

Rules:

1. Only close direct paths (never relay - they’re fallback)
2. Don’t close the selected path
3. Keep at least min_direct_paths direct paths open

pub fn update_rtt(&mut self, addr: &SocketAddr, rtt: Duration)

Update RTT for a path

pub fn mark_open(&mut self, addr: &SocketAddr)

Mark a path as open

pub fn mark_closed(&mut self, addr: &SocketAddr)

Mark a path as closed
