Trait DrizzleRowByIndex 

pub trait DrizzleRowByIndex {
    // Required method
    fn get_column<T: FromPostgresValue>(
        &self,
        idx: usize,
    ) -> Result<T, DrizzleError>;
}

A driver row whose columns can be read by position.

Required Methods

fn get_column<T: FromPostgresValue>( &self, idx: usize, ) -> Result<T, DrizzleError>

Reads column idx (zero-based) as T.

Errors

Returns DrizzleError if the column is out of bounds, the value is NULL for a non-nullable target, or the stored value cannot be converted into T.

Dyn Compatibility

This trait is not dyn compatible.

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