    ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

Field guard

Guard is a pre-condition for a field that is resolved if Ok(()) is returned, otherwise an error is returned.

This trait is defined through the async-trait macro.

Required methods

fn check<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    ctx: &'life1 Context<'life2>
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: 'async_trait,
    Self: 'async_trait, 

Check whether the guard will allow access to the field.
