Trait BindIndex 

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

A trait implemented by types that can index into parameters of a statement.

It is only implemented for usize and &str and &CStr.

Required Methods

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

Returns the index of the associated parameter, or Error if no such parameter exists.

Dyn Compatibility

This trait is dyn compatible.

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