Enum NodeState 

pub enum NodeState {
    Idle,
    Processing,
    Done,
    Error,
}

State of a node during graph execution.

Variants

Idle

Node is idle and ready to process.

Processing

Node is currently processing.

Done

Node has finished processing (end of stream).

Error

Node encountered an error.

Implementations

impl NodeState

pub fn can_transition_to(&self, new_state: Self) -> bool

Check if the node can transition to the given state.

Trait Implementations

impl Clone for NodeState

fn clone(&self) -> NodeState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeState

impl Debug for NodeState

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

Formats the value using the given formatter.

impl Default for NodeState

fn default() -> NodeState

Returns the “default value” for a type.

impl Display for NodeState

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

Formats the value using the given formatter.

impl Eq for NodeState

impl PartialEq for NodeState

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