TabLock

chat_platform_native::tab_lock

Struct TabLock 

Source 
pub struct TabLock { /* private fields */ }
Expand description

A cross-platform tab-lock (single-instance lock).

On native targets this uses an exclusive file lock via fs2. On wasm32 this is a no-op stub because only one WASM instance runs per browser tab anyway; Phase 5 may add web-sys BroadcastChannel locking.

Implementations§

Source§

impl TabLock

Source

pub fn try_acquire(path: &Path) -> Option<TabLock>

Attempt to acquire the lock. Returns Some(TabLock) on success, or None if another instance already holds the lock.
