A set of common methods for ConcreteLookAheadSelection and LookAheadSelection

Required Methods

`fn field_name(&self) -> &str`

Get the name of the field represented by the current selection

`fn select_child(&self, name: &str) -> Option<&Self>`

Get the the child selection for a given field

`fn arguments(&self) -> &[LookAheadArgument]`

Get the top level arguments for the current selection

Provided Methods

`fn has_child(&self, name: &str) -> bool`

Check if a given field exists

`fn argument(&self, name: &str) -> Option<&LookAheadArgument>`

Get the top level argument with a given name from the current selection
