Setting trait bounds on objects created within a function

Question

I'm fooling around with the ipc-channel crate, trying to build a generic struct that holds an IpcOneShotServer:

extern crate ipc_channel;
extern crate serde;

use ipc_channel::{ipc, Error};
use serde::{Deserialize, Serialize};

struct Supervisor<T> {
    server: ipc::IpcOneShotServer<T>,
}

impl<T> Supervisor<T>
where
    T: for<'de> Deserialize<'de> + Serialize,
{
    fn new() -> Result<Supervisor<T>, Error> {
        let (server, _) = ipc::IpcOneShotServer::new()?;
        Ok(Supervisor { server: server })
    }
}

fn main() {}

When I try to compile this code, I get the following errors

error[E0277]: the trait bound `for<'de> T: serde::de::Deserialize<'de>` is not satisfied
  --> src/main.rs:67:27
   |

   = note: required by `<ipc_channel::ipc::IpcOneShotServer<T>>::new`

I'm not sure what I'm missing here. I have bounded the trait T by both Deserialize and Serialize. I thought that by binding the trait in the impl by those two other traits this would tell the type checker that as long as a Supervisor of type T implements Deserialize and Serialize it's safe to call ipc::IpcOneShotServer::new().
