Struct async_graphql::context::QueryPathNode[−][src]

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

A path to the current query.

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

Fields

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

The parent node to this, if there is one.

segment: QueryPathSegment<'a>
Expand description

The current path segment being resolved.

Implementations

impl<'a> QueryPathNode<'a>[src]

pub fn field_name(&self) -> &str[src]

Get the current field name.

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

#[must_use]
pub fn to_string_vec(&self) -> Vec<String>[src]

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

pub fn parents(&self) -> Parents<'_>ⓘ

Notable traits for Parents<'a>

impl<'a> Iterator for Parents<'a> type Item = &'a QueryPathNode<'a>;
[src]

Iterate over the parents of the node.
