Enum NodeOutput 

pub enum NodeOutput {
    Data {
        data: Value,
    },
    Errors {
        errors: Vec<NodeError>,
    },
}

A node’s output: success carries {data}, failure carries {errors}. The two are mutually exclusive (enforced by the type); engine metadata lives in a sibling meta, never inside data.

Variants

Data

Success: arbitrary node-defined fields under data.

Fields

data: Value

The success payload.

Errors

Failure: one or more errors under errors.

Fields

errors: Vec<NodeError>

The error list (a node may report several validation failures at once).

Implementations

impl NodeOutput

pub fn ok(data: Value) -> Self

Build a success output { data }.

pub fn failed(errors: Vec<NodeError>) -> Self

Build a failure output { errors }.

pub fn is_ok(&self) -> bool

true when this is a success ({data}) output.

pub fn data(&self) -> Option<&Value>

The success payload, or None on a failure output.

pub fn errors(&self) -> &[NodeError]

The error list, or an empty slice on a success output.

Trait Implementations

impl Clone for NodeOutput

fn clone(&self) -> NodeOutput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeOutput

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeOutput

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NodeOutput

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

impl Serialize for NodeOutput

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
