Struct NodeError 

#[non_exhaustive]
pub struct NodeError { /* private fields */ }

A unified error used by node lifecycle methods.

Implementations

impl NodeError

pub const fn new(kind: NodeErrorKind, code: u32) -> Self

Construct a new node error with the given kind and optional code.

impl NodeError

pub const fn no_input() -> Self

Creates a NoInput error.

pub const fn backpressured() -> Self

Creates a Backpressured error.

pub const fn over_budget() -> Self

Creates an OverBudget error.

pub const fn external_unavailable() -> Self

Creates an ExternalUnavailable error.

pub const fn execution_failed() -> Self

Creates an ExecutionFailed error.

pub const fn with_code(self, code: u32) -> Self

Same as the above but lets you tack on a backend/platform error code.

pub const fn kind(&self) -> &NodeErrorKind

Return the error kind.

pub const fn code(&self) -> &u32

Return the numeric code associated with this error.

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

Available on crate feature std only.

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 From<NodeError> for RuntimeError

fn from(e: NodeError) -> Self

Converts to this type from the input type.

impl From<NodeErrorKind> for NodeError

fn from(kind: NodeErrorKind) -> Self

Converts to this type from the input type.

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.
