Struct PersistedSession 

pub struct PersistedSession {
    pub home_dc_id: i32,
    pub dcs: Vec<DcEntry>,
    pub updates_state: UpdatesStateSnap,
    pub peers: Vec<CachedPeer>,
    pub min_peers: Vec<CachedMinPeer>,
}

Everything that needs to survive a process restart.

Fields

home_dc_id: i32

dcs: Vec<DcEntry>

updates_state: UpdatesStateSnap

Update counters to enable reliable catch-up after a disconnect.

peers: Vec<CachedPeer>

Peer access-hash cache so that the client can reach out to any previously seen user or channel without re-resolving them.

min_peers: Vec<CachedMinPeer>

Min-user message contexts: users seen with min=true that can only be addressed via InputPeerUserFromMessage.

Implementations

impl PersistedSession

pub fn to_bytes(&self) -> Vec<u8>

Encode the session to raw bytes (v2 binary format).

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

Atomically save the session to path.

Writes to <path>.tmp first, then renames into place so a crash mid-write never corrupts the existing session file.

pub fn from_bytes(buf: &[u8]) -> Result<Self>

Decode a session from raw bytes (v1 or v2 binary format).

pub fn from_string(s: &str) -> Result<Self>

Decode a session from a URL-safe base64 string produced by [to_string].

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

pub fn dc_for(&self, dc_id: i32, prefer_ipv6: bool) -> Option<&DcEntry>

Find the best DC entry for a given DC ID.

When prefer_ipv6 is true, returns the IPv6 entry if one is stored, falling back to IPv4. When false, returns IPv4, falling back to IPv6. Returns None only when the DC ID is completely unknown.

This correctly handles the case where both an IPv4 and an IPv6 DcEntry exist for the same dc_id (different flags bitmask).

pub fn all_dcs_for(&self, dc_id: i32) -> impl Iterator<Item = &DcEntry>

Iterate over every stored DC entry for a given DC ID.

Typically yields one IPv4 and one IPv6 entry per DC ID once help.getConfig has been applied.
