Struct NodeMetadata 

pub struct NodeMetadata {
    pub node_type: String,
    pub name: String,
    pub description: String,
    pub category: NodeCategory,
    pub accepts: Vec<String>,
    pub platforms: Vec<String>,
    pub parameters: Vec<ParameterDef>,
    pub input_cardinality: InputCardinality,
    pub requires: Vec<Dependency>,
}

Complete self-description of a processor. Return type of NodeProcessor::metadata(). The node_type is the direct dispatch key (e.g., "image-compress").

Fields

node_type: String

Per-operation node type (e.g., "image-compress", "spreadsheet-clean").

name: String

Human-readable processor name.

description: String

Description of what this processor does.

category: NodeCategory

Category for UI grouping/filtering.

accepts: Vec<String>

Accepted MIME types. Empty means “any file type”.

platforms: Vec<String>

Platforms this processor runs on ("browser", "server", "desktop").

parameters: Vec<ParameterDef>

Parameters with types, defaults, and constraints.

input_cardinality: InputCardinality

How this processor expects to receive files: one at a time or as a batch. Defaults to PerFile. Used by the auto-iteration executor.

requires: Vec<Dependency>

External binary dependencies. Empty for browser-only processors.

Trait Implementations

impl Clone for NodeMetadata

fn clone(&self) -> NodeMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeMetadata

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

Formats the value using the given formatter.

impl PartialEq for NodeMetadata

fn eq(&self, other: &NodeMetadata) -> 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 NodeMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
