Struct CloseGroupCache 

pub struct CloseGroupCache {
    pub peers: Vec<CachedCloseGroupPeer>,
    pub saved_at_epoch_secs: u64,
}

Persisted close group snapshot with trust scores.

Saved periodically and on shutdown. Loaded on startup to reconnect to the same trusted close group peers, preserving close group consistency across restarts.

Fields

peers: Vec<CachedCloseGroupPeer>

Close group peers with their trust scores

saved_at_epoch_secs: u64

When this snapshot was saved (seconds since UNIX epoch)

Implementations

impl CloseGroupCache

pub async fn save_to_dir(&self, dir: &Path) -> Result<()>

Save the cache to {dir}/close_group_cache.json.

Uses tempfile::NamedTempFile::persist for atomicity: the temp file has a unique name (safe under concurrent saves) and persist is an atomic rename on Unix and a replace-then-rename on Windows.

pub async fn load_from_dir(dir: &Path) -> Result<Option<Self>>

Load the cache from {dir}/close_group_cache.json.

Returns None if the file doesn’t exist (fresh start).
