Enum NodeError 

#[non_exhaustive]
pub enum NodeError {
    Handler(String),
    InvalidInput(String),
    BackpressureDrop(String),
}

Structured node error for better diagnostics.

use daedalus_runtime::executor::NodeError;
let err = NodeError::InvalidInput("missing".into());
assert_eq!(err.code(), "invalid_input");

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Handler(String)

InvalidInput(String)

BackpressureDrop(String)

Implementations

impl NodeError

pub fn code(&self) -> &'static str

Return a stable string code for this error.

pub fn retryable(&self) -> bool

Whether the error is retryable.

Trait Implementations

impl Clone for NodeError

fn clone(&self) -> NodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeError

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

Formats the value using the given formatter.

impl Display for NodeError

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

Formats the value using the given formatter.

impl Error for NodeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for NodeError

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