Required Associated Types

type Error: Into<Error>

Required Methods

fn filter( &mut self, idx_num: i32, idx_str: Option<&str>, args: &[ValueRef<'_>], ) -> Result<(), Self::Error>

fn next(&mut self) -> Result<(), Self::Error>

fn eof(&self) -> bool

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.
