Provided Methods

fn results<T>( &self, offset: u32, sink: &mut [T], flags: QueryResultFlags, ) -> QueryResult<()>

Available on crate feature Implements only.

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.
