Trait RowIndex 

pub trait RowIndex: Sealed {
    // Required method
    fn idx(&self, stmt: &Statement<'_>) -> Result<usize>;
}

A trait implemented by types that can index into columns of a row.

It is only implemented for usize and &str.

Required Methods

fn idx(&self, stmt: &Statement<'_>) -> Result<usize>

Returns the index of the appropriate column, or None if no such column exists.

Dyn Compatibility

This trait is dyn compatible.

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

Implementations on Foreign Types
