Implementations§

Source§

impl NodeDefinition

Source

pub fn compile( nodes: HashMap<String, NodeSpec>, ) -> HashMap<String, NodeDefinition>

§参数
  • nodes: 节点名称到NodeSpec的映射
§返回值

返回HashMap<String, [NodeType]> 类型节点集合

Source

pub fn new(name: String, spec: NodeSpec) -> Self

创建新的节点类型实例

§参数
  • name: 节点类型名称
