Enum Direction 

pub enum Direction {
    Out,
    In,
}

Edge direction a CSR file is keyed by.

Out means rows are keyed by src_id and neighbors are destinations; In means rows are keyed by dst_id and neighbors are sources. Undirected traversal is served by unioning the two — there is no undirected file on disk.

Variants

Out

Outgoing edges: keyed by src_id, neighbor is dst_id.

In

Incoming edges: keyed by dst_id, neighbor is src_id.

Implementations

impl Direction

pub fn as_str(self) -> &'static str

The on-disk token ("out" | "in") used in file names and the manifest direction column.

pub fn parse(s: &str) -> Result<Self, GfError>

Parse a manifest direction token.

Errors

Returns GfError::Storage for anything other than "out" / "in".
