Required Methods

fn write_columnar<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, calls: &'life1 CallSlot, batch: &'life2 RecordBatch, ) -> Pin<Box<dyn Future<Output = Result<usize, FaucetError>> + Send + 'async_trait>>

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

Write a record batch, returning the rows written.

This trait is dyn compatible.

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