Struct NodeMeta 

pub struct NodeMeta {
    pub name: String,
    pub effectful: bool,
    pub kind: FilterKind,
    pub cacheable: bool,
    pub deterministic: bool,
    pub differentiable: bool,
    pub distribution: Distribution,
    pub input_schema: Option<Schema>,
    pub output_schema: Option<Schema>,
}

A node’s contract, independent of whether it computes or acts.

Fields

name: String

The name/type identifier of the implementation behind this node.

effectful: bool

Does it reach outside the graph — models, tools, people?

The one thing downstream genuinely needs to tell apart: an effectful node is journaled rather than memoized, and it is reported as itself in events instead of borrowing a FilterKind.

kind: FilterKind

Classification of a computational node’s behaviour.

FilterKind::Opaque for an effectful node, which has no trained state to speak of.

cacheable: bool

May this node’s output be cached?

deterministic: bool

Same inputs, same output? See FilterMeta::deterministic.

differentiable: bool

Does forward() keep a differentiable graph?

distribution: Distribution

Where it may run.

input_schema: Option<Schema>

What it accepts (None = anything).

output_schema: Option<Schema>

What it produces (None = unknown).

Implementations

impl NodeMeta

pub fn trainable(&self) -> bool

Is there trained state to learn and cache?

impl NodeMeta

pub fn as_filter_meta(&self) -> FilterMeta

The computational half, for consumers that only speak FilterMeta.

Lossy by design: an effectful node has no honest FilterMeta, and callers should ask NodeMeta::effectful before reaching for this.

Trait Implementations

impl Clone for NodeMeta

fn clone(&self) -> NodeMeta

Returns a duplicate of the value.

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