Hi,

I try to use DataLoader with async-graphq.
But I got a lifetime problem that I do not understand.

The profile of the function load is :

/// Trait for batch loading.
#[cfg_attr(feature = "boxed-trait", async_trait::async_trait)]
pub trait Loader<K: Send + Sync + Hash + Eq + Clone + 'static>: Send + Sync + 'static {
    /// type of value.
    type Value: Send + Sync + Clone + 'static;

    /// Type of error.
    type Error: Send + Clone + 'static;

    /// Load the data set specified by the `keys`.
    #[cfg(feature = "boxed-trait")]
    async fn load(&self, keys: &[K]) -> Result<HashMap<K, Self::Value>, Self::Error>;

And I try to use String or SomeStruct(String) as keys...

#[async_trait]
impl Loader<String> for ParameteByIdLoader {
    type Value = Parameter;
    type Error = async_graphql::Error;

    async fn load(
        &self,
        ids: &[String],
    ) -> Result<HashMap<String, Self::Value>, Self::Error> {

       ...

I have the following error :

error[E0195]: lifetime parameters or bounds on method `load` do not match the trait declaration
  ...
   |
49 |       async fn load(
   |  ______________^
50 | |         &self,
51 | |         ids: &[String],
52 | |     ) -> Result<HashMap<String, Self::Value>, Self::Error> {
   | |_____^ lifetimes do not match method in trait

Can you help me on what usage I am wrong, please ?
