Trait Implementations

impl<'a, S: Debug + 'a> Debug for ConcreteLookAheadSelection<'a, S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, S> LookAheadMethods<'a, S> for ConcreteLookAheadSelection<'a, S>

fn field_name(&self) -> &'a str

Get the (potentially aliased) 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 If a child has an alias, it will only match if the alias matches name

fn arguments(&self) -> &[LookAheadArgument<'_, S>]

Get the top level arguments for the current selection

fn child_names(&self) -> Vec<&'a str>

Get the (possibly aliased) names of the top level children for the current selection

fn has_arguments(&self) -> bool

Does the current node have any arguments?

fn has_children(&self) -> bool

Does the current node have any children?

fn children(&self) -> Vec<&Self>

Get an iterator over the children for the current selection

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

Check if a given child selection with a name exists If a child has an alias, it will only match if the alias matches name

fn argument(&self, name: &str) -> Option<&LookAheadArgument<'_, S>>

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

impl<'a, S: PartialEq + 'a> PartialEq<ConcreteLookAheadSelection<'a, S>> for ConcreteLookAheadSelection<'a, S>

fn eq(&self, other: &ConcreteLookAheadSelection<'a, S>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
