Implementations

impl TraverserValue

pub fn as_vertex_id(&self) -> Option<&str>

Get as vertex ID if applicable

pub fn as_edge(&self) -> Option<(&str, &str, &str, &str)>

Get as edge info if applicable

pub fn is_null(&self) -> bool

Check if null

pub fn to_json(&self) -> Value

Convert to JSON value

Trait Implementations

impl Clone for TraverserValue

fn clone(&self) -> TraverserValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraverserValue

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

Formats the value using the given formatter.

impl Hash for TraverserValue

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TraverserValue

fn eq(&self, other: &TraverserValue) -> 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.
