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

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

Get the (potentially aliased) name of the field represented by the current selection

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

👎 Deprecated:

please use children to access the child selections instead

Get the the child selection for a given field If a child has an alias, it will only match if the alias matches name

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

Get the top level arguments for the current selection

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

👎 Deprecated:

please use children to access the child selections instead

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

pub fn has_arguments(&self) -> bool

Does the current node have any arguments?

pub fn has_children(&self) -> bool

Does the current node have any children?

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

Get an iterator over the children for the current selection

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

👎 Deprecated:

please use children to access the child selections instead

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

pub 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<LookAheadSelection<'a, S>> for LookAheadSelection<'a, S>

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

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

pub fn ne(&self, other: &LookAheadSelection<'a, S>) -> bool

This method tests for !=.
