Struct PathQuery

    pub alias: Option<String>,
    pub from: NodeSelector,
    pub to: NodeSelector,
    pub via: Vec<String>,
    pub max_length: u32,

    pub return_: Vec<Projection>,
}

Path query: find paths between nodes

Fields

alias: Option<String>

Optional outer alias when used as a join source

from: NodeSelector

Source node selector

to: NodeSelector

Target node selector

via: Vec<String>

Edge labels to traverse (empty = any). Strings are resolved against the runtime registry by the executor.

max_length: u32

Maximum path length

filter: Option<Filter>

Filter on paths

return_: Vec<Projection>

Return projections

Implementations

impl PathQuery

pub fn new(from: NodeSelector, to: NodeSelector) -> PathQuery

Create a new path query

pub fn alias(self, alias: &str) -> PathQuery

Set outer alias

pub fn via_label(self, label: impl Into<String>) -> PathQuery

Add an edge label constraint to traverse (string form).

fn clone(&self) -> PathQuery

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
