apoc.date — 5 functions

Function	Description
parse(s: &str, format: &str) -> Result<i64, String>	Parse a date string in a given format. Supports: "epoch", "iso".
format_epoch(epoch_secs: i64, format: &str) -> String	Format an epoch timestamp to a string.
add(epoch_secs: i64, amount: i64, unit: &str) -> Result<i64, String>	Add a duration to an epoch timestamp.
diff(epoch1: i64, epoch2: i64, unit: &str) -> Result<i64, String>	Difference between two epoch timestamps in the specified unit.

apoc.import_export — 6 functions

Function	Description
export_json_all(graph: &dyn Graph) -> String	Export all nodes and relationships to a JSON string.
export_csv_all(graph: &dyn Graph) -> (String, String)	Export all nodes and relationships to CSV strings. Returns (nodes_csv, relationships_csv).
import_json_nodes(graph: &mut dyn Graph, json: &str) -> Result<usize, String>	Import nodes from a simple JSON format into the graph. Expected: [{"labels": [1], "properties": {"1": "value"}}, ...]
import_csv_nodes(graph: &mut dyn Graph, csv: &str) -> Result<usize, String>	Import nodes from CSV. First line is header.
load_json_url(_url: &str) -> Result<String, String>	Stub: load JSON from a URL. Returns the raw string.
load_csv_url(_url: &str) -> Result<String, String>	Stub: load CSV from a URL.

apoc.math — 7 functions

apoc.refactor — 6 functions

Function	Description
merge_nodes(	Merge multiple nodes into one, combining properties and relationships. Returns the ID of the surviving node (first in the list).
clone_nodes(graph: &mut dyn Graph, node_ids: &[NodeId]) -> Vec<NodeId>	Clone nodes with their properties. Returns new node IDs.
clone_subgraph(	Clone a subgraph (nodes + relationships). Returns (new_node_ids, new_rel_ids).
rename_label(graph: &mut dyn Graph, old_label: LabelId, new_label: LabelId) -> usize	Rename a label across all nodes.
rename_rel_type(	Rename a relationship type. Since rel type is immutable, this deletes and recreates each relationship with the new type.
rename_property(	Rename a property key across all nodes.

apoc.spatial — 5 functions

Function	Description
distance(lat1: f64, lon1: f64, lat2: f64, lon2: f64) -> f64	Haversine distance between two lat/lon points, in meters.

sort_by_distance(points: &mut [(f64, f64, u64)], center_lat: f64, center_lon: f64)	Sort a list of (lat, lon, id) by distance from a center point.
geocode(_address: &str) -> Option<(f64, f64)>	Geocode stub — returns None (real implementation would call an external API).
bounding_box(lat: f64, lon: f64, distance_meters: f64) -> (f64, f64, f64, f64)	Compute a bounding box around a center point at a given distance. Returns (min_lat, min_lon, max_lat, max_lon).
