Trait QueryNodes 

pub trait QueryNodes {
    // Required methods
    fn query_nodes<'a, Q, R>(&'a self, query: Q) -> Selection<'a, R>
       where Q: FnOnce(&NodesOperand<Unordered>) -> R,
             R: ReturnOperand<'a>;
    fn query_nodes_with<'a, Q, R>(
        &'a self,
        optimizer: &Optimizer,
        query: Q,
    ) -> Selection<'a, R>
       where Q: FnOnce(&NodesOperand<Unordered>) -> R,
             R: ReturnOperand<'a>;
}

Required Methods

fn query_nodes<'a, Q, R>(&'a self, query: Q) -> Selection<'a, R>

where Q: FnOnce(&NodesOperand<Unordered>) -> R, R: ReturnOperand<'a>,

fn query_nodes_with<'a, Q, R>( &'a self, optimizer: &Optimizer, query: Q, ) -> Selection<'a, R>

where Q: FnOnce(&NodesOperand<Unordered>) -> R, R: ReturnOperand<'a>,

Dyn Compatibility

This trait is not dyn compatible.

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