Trait germinate::ValueLoader

pub trait ValueLoader {
#[must_use]    fn load<'life0, 'life1, 'async_trait>(
        &'life0 self, 
        key: &'life1 String
    ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>
    where
        'life0: 'async_trait,
        'life1: 'async_trait,
        Self: 'async_trait;
}

A type implementing the ValueLoader trait can be used to load a value from a store by it's key

For example, the type could load a value from and environment variable, or an external key value store like etcd.

As the value could be loaded from an external network source, it must be done asynchronously to allow non-blocking value loading

Loads a value from the Parameter Store and returns it as a String

impl ValueLoader for EnvironmentLoader

fn load<'life0, 'life1, 'async_trait>(
    &'life0 self,
    key: &'life1 String
) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait,
