Field guard

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

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 Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Check whether the guard will allow access to the field.
