Struct NetworkState 

pub struct NetworkState {
    pub version: u32,
    pub networks: Vec<ManagedNetwork>,
}

The full marker file: every host-level network this node manages.

Fields

version: u32

On-disk schema version.

networks: Vec<ManagedNetwork>

Managed networks, keyed in practice by ManagedNetwork::owner.

Implementations

impl NetworkState

pub fn load(path: &Path) -> Self

Load the marker file. A missing or unparseable file yields an empty state rather than an error — the marker is a best-effort cache that the live-host enumeration paths can always rebuild.

pub fn save(&self, path: &Path) -> Result<()>

Persist the marker file, creating the parent directory if needed. Writes to a sibling temp file and renames so a crash mid-write can’t leave a truncated marker.

Errors

Returns any I/O error from creating the directory, writing, or renaming.

pub fn get(&self, owner: &str) -> Option<&ManagedNetwork>

Look up a managed network by owner.

pub fn upsert(&mut self, net: ManagedNetwork)

Insert or replace the entry for net.owner.

pub fn remove(&mut self, owner: &str) -> Option<ManagedNetwork>

Remove and return the entry for owner, if present.
