Struct LuaHook 

pub struct LuaHook { /* private fields */ }

A hook backed by a Lua function.

The handler function is stored in Lua’s registry via mlua::RegistryKey. A cloned Lua handle provides thread-safe access to the same Lua state (mlua uses internal locking with the send feature).

Thread-safety: Mutex<Lua> is Send + Sync because Lua: Send.

Implementations

impl LuaHook

pub fn new( id: String, fql: FqlPattern, point: HookPoint, priority: i32, lua: &Lua, func: &Function, ) -> Result<Self, Error>

Creates a new LuaHook.

Stores func in Lua’s registry and clones the Lua handle for later invocation from any thread.

Errors

Returns an error if the function cannot be stored in the registry.
