Trait ReadableWithIndex

pub trait ReadableWithIndex: Sized {
    // Required method
    fn read<T: ColumnIndex>(_: &Statement, _: T) -> Result<Self>;
}

A type suitable for reading from a prepared statement given a column index.

Required Methods

fn read<T: ColumnIndex>(_: &Statement, _: T) -> Result<Self>

Read from a column.

In case of integer indices, the first column has index 0.

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.
