Trait ColumnIndex

pub trait ColumnIndex: Copy + Debug {
    // Required method
    fn index(self, statement: &Statement<'_>) -> Result<usize>;
}

A type suitable for indexing columns in a prepared statement.

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.
