Trait IntoPlanExecutionError 

pub trait IntoPlanExecutionError<T> {
    // Required method
    fn with_plan_context<SN, AP>(
        self,
        context: LazyPlanContext<SN, AP>,
    ) -> Result<T, PlanExecutionError>
       where SN: FnOnce() -> Option<String>,
             AP: FnOnce() -> Option<String>;
}

An extension trait for Result types that can be converted into a PlanExecutionError.

This trait provides a lazy, performant way to add contextual information to an error, only performing work (like cloning strings) if the Result is an Err.

Required Methods

fn with_plan_context<SN, AP>( self, context: LazyPlanContext<SN, AP>, ) -> Result<T, PlanExecutionError>

where SN: FnOnce() -> Option<String>, AP: FnOnce() -> Option<String>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
