Associated Types

type Database: Database

Required methods

fn ordinal(&self) -> usize

Gets the column ordinal.

This can be used to unambiguously refer to this column within a row in case more than one column have the same name

fn name(&self) -> &str

Gets the column name or alias.

The column name is unreliable (and can change between database minor versions) if this column is an expression that has not been aliased.

fn type_info(&self) -> &<Self::Database as Database>::TypeInfo

Gets the type information for the column.
