Variables ¶
var ErrRuntimeClosed = errors.New("luart: runtime is closed")
ErrRuntimeClosed is returned when Exec is called after Close.
var ErrVMPoolExhausted = errdefs.NotAvailable(errors.New("luart: VM pool exhausted, context cancelled while waiting"))
ErrVMPoolExhausted is returned when all VMs are in use and the context is cancelled before one becomes available.

Types ¶
type Runtime ¶
type Runtime struct {
// contains filtered or unexported fields
}
Runtime manages a pool of gopher-lua VMs for Lua script execution. It implements script.Runtime. Close is safe to call multiple times.
func (*Runtime) Close ¶
Close drains the VM pool and closes every LState. It is safe to call multiple times; subsequent calls are no-ops.
func (*Runtime) Exec ¶
func (r *Runtime) Exec(ctx context.Context, name, source string, env *script.Env) (*script.Signal, error)
Exec implements script.Runtime. It runs Lua in a pooled LState with config and bindings as globals. A built-in "signal" global is always injected for interrupt/error/done control flow back to the host.
