Struct QueryPathNode

pub struct QueryPathNode<'a> {
    pub parent: Option<&'a QueryPathNode<'a>>,
    pub segment: QueryPathSegment<'a>,
}

A path to the current query.

The path is stored as a kind of reverse linked list.

Fields

parent: Option<&'a QueryPathNode<'a>>

The parent node to this, if there is one.

segment: QueryPathSegment<'a>

The current path segment being resolved.

Implementations

impl<'a> QueryPathNode<'a>

pub fn field_name(&self) -> &str

Get the current field name.

This traverses all the parents of the node until it finds one that is a field name.

pub fn to_string_vec(self) -> Vec<String>

Get the path represented by Vec<String>; numbers will be stringified.

pub fn parents(&self) -> Parents<'_>

Iterate over the parents of the node.
