Struct BindNode 

pub struct BindNode { /* private fields */ }

Binds the output of a child node into the render context without emitting it.

This is the node generated for {% alias:rule %} statements. If alias is not already bound, it renders rule and stores the result under alias. It also supports {% alias:=rule %} statements, which always render rule and overwrite alias. Binding statements always return an empty string so later {alias} references reuse the generated value.
