Implementations

impl QueryNode

pub fn leaf(field: impl Into<String>, type_name: impl Into<String>) -> Self

Create a leaf node (no children, not a list).

pub fn with_children( field: impl Into<String>, type_name: impl Into<String>, children: Vec<QueryNode>, ) -> Self

Create a non-list node with children.

pub fn list_field( field: impl Into<String>, type_name: impl Into<String>, children: Vec<QueryNode>, ) -> Self

Create a list field node with children.

pub fn depth(&self) -> usize

Depth of this node’s subtree (leaf = 1).

pub fn field_count(&self) -> usize

Total number of fields (nodes) in this subtree.
