Struct SessionGuard

Source

pub struct SessionGuard { /* private fields */ }

Expand description

Lightweight handle that remembers the session generation at the moment it was created. Pass it into background tasks (via move-capture into a spawned future) and check is_valid() before any side-effect.

Cheap to copy — just a u64. Never holds a lock.

Implementations§

Source §

impl SessionGuard

Source

pub fn capture() -> Self

Snapshot the current session generation for later validation.

Source

pub fn is_valid(&self) -> bool

true while the captured generation still matches the live counter. Once false, any captured per-account context (npub, keys, chat ids) is no longer guaranteed to belong to the active session.

Source

pub fn generation(&self) -> u64

Raw generation value (for logging / structured comparisons).
