Trait RowSink 

pub trait RowSink: Send {
    // Required methods
    fn expects(&self) -> &[Option<SqlType>];
    fn row(&mut self, row: &mut dyn ColumnReader) -> Result<()>;
}

Required Methods

fn expects(&self) -> &[Option<SqlType>]

Checked once before any row is read; None takes any type, fewer columns are refused.

fn row(&mut self, row: &mut dyn ColumnReader) -> Result<()>

Dyn Compatibility

This trait is dyn compatible.

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