Trait ComputedFieldHook 

pub trait ComputedFieldHook: Send + Sync {
    // Required method
    fn resolve<'life0, 'life1, 'async_trait>(
        &'life0 self,
        record: Value,
        fields: &'life1 [(String, String)],
    ) -> Pin<Box<dyn Future<Output = Result<Value, String>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Hook for computing virtual field values at read time.

Required Methods

fn resolve<'life0, 'life1, 'async_trait>( &'life0 self, record: Value, fields: &'life1 [(String, String)], ) -> Pin<Box<dyn Future<Output = Result<Value, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Resolve computed fields for a record.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
