Enum EdgeDirection

pub enum EdgeDirection {
    Outbound,
    Inbound,
}

Specifies what kind of items should be piped from one type of query to another.

Edge and vertex queries can build off of one another via pipes - e.g. you can get the outbound edges of a set of vertices by piping from a vertex query to an edge query. EdgeDirections are used to specify which end of things you want to pipe - either the outbound items or the inbound items.

Variants

Outbound

Outbound direction.

Inbound

Inbound direction.

Trait Implementations

impl Clone for EdgeDirection

fn clone(&self) -> EdgeDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeDirection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<EdgeDirection> for String

fn from(d: EdgeDirection) -> Self

Converts to this type from the input type.

impl FromStr for EdgeDirection

type Err = ValidationError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<EdgeDirection, Self::Err>

impl PartialEq for EdgeDirection

fn eq(&self, other: &EdgeDirection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
