Hi Josh,
We tried to run servo with our modified devices crate.
Now we are getting the following errors,
error[E0277]: the size for values of type `(dyn
device::adapter::BluetoothAdapter + 'static)` cannot be known at
compilation time
--> components/bluetooth/lib.rs:193:5
|
193 | adapter: Option<BluetoothAdapter>,
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ doesn't have a size known at
compile-time
|
= help: the trait `std::marker::Sized` is not implemented for `(dyn
device::adapter::BluetoothAdapter + 'static)`
= note: required by `std::option::Option`
/////
error[E0277]: the size for values of type `(dyn
device::adapter::BluetoothAdapter + 'static)` cannot be known at
compilation time
--> components/bluetooth/lib.rs:338:5
|
338 | / fn get_adapter(&mut self) -> BluetoothResult<BluetoothAdapter> {
339 | | match self.get_or_create_adapter() {
340 | | Some(adapter) => {
341 | | if !adapter.is_powered().unwrap_or(false) {
... |
347 | | }
348 | | }
| |_____^ doesn't have a size known at compile-time
|
error: aborting due to 4 previous errors
I tried to replace Option<BluetoothAdapter> with
Option<Box<BluetoothAdapter> which only gave out more errors.
