Trait LineProtocolInterceptor 

pub trait LineProtocolInterceptor {
    type Error: ErrorExt;

    // Provided methods
    fn pre_execute(
        &self,
        _line: &str,
        _query_ctx: QueryContextRef,
    ) -> Result<(), Self::Error> { ... }
    fn post_lines_conversion<'life0, 'async_trait>(
        &'life0 self,
        requests: RowInsertRequests,
        query_context: QueryContextRef,
    ) -> Pin<Box<dyn Future<Output = Result<RowInsertRequests, Self::Error>> + Send + 'async_trait>>
       where Self: Sync + 'async_trait,
             'life0: 'async_trait { ... }
}

LineProtocolInterceptor can track life cycle of a line protocol request and customize or abort its execution at given point.

Required Associated Types

type Error: ErrorExt

Provided Methods

fn pre_execute( &self, _line: &str, _query_ctx: QueryContextRef, ) -> Result<(), Self::Error>

fn post_lines_conversion<'life0, 'async_trait>( &'life0 self, requests: RowInsertRequests, query_context: QueryContextRef, ) -> Pin<Box<dyn Future<Output = Result<RowInsertRequests, Self::Error>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Called after the lines are converted to the [RowInsertRequests]. We can then modify the resulting requests if needed. Typically used in some backward compatibility situation.

Dyn Compatibility

This trait is dyn compatible.

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