Source

fn id(&self) -> &NodeId

Get the node’s unique identifier

Source

fn name(&self) -> &str

Get the node’s display name

Provided Methods§

Source

fn description(&self) -> Option<&str>

Get the node’s description

Source

fn input_keys(&self) -> Vec<&str>

Get the expected input keys from the state

Source

fn output_keys(&self) -> Vec<&str>
