Struct NodeError 

pub struct NodeError {
    pub code: String,
    pub message: String,
    pub retryable: bool,
    pub backoff_ms: Option<u64>,
    pub details: Option<ErrorDetail>,
    /* private fields */
}

Error type emitted by Greentic nodes.

Fields

code: String

Machine readable error code.

message: String

Human readable message explaining the failure.

retryable: bool

Whether the failure is retryable by the runtime.

backoff_ms: Option<u64>

Optional backoff duration in milliseconds for the next retry.

details: Option<ErrorDetail>

Optional structured error detail payload.

Implementations

impl NodeError

pub fn new(code: impl Into<String>, message: impl Into<String>) -> NodeError

Constructs a non-retryable failure with the supplied code and message.

pub fn with_retry(self, backoff_ms: Option<u64>) -> NodeError

Marks the error as retryable with an optional backoff value.

pub fn with_detail(self, detail: ErrorDetail) -> NodeError

Attaches structured details to the error.

pub fn with_detail_text(self, detail: impl Into<String>) -> NodeError

Attaches a textual detail payload to the error.

pub fn with_detail_binary(self, detail: Vec<u8>) -> NodeError

Attaches a binary detail payload to the error.

pub fn with_source<E>(self, source: E) -> NodeError

where E: Error + Send + Sync + 'static,

Attaches a source error to the failure for debugging purposes.

pub fn detail(&self) -> Option<&ErrorDetail>

Returns the structured details, when available.

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

Returns the attached source error when one has been provided.

Trait Implementations

impl Debug for NodeError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeError

fn deserialize<__D>( __deserializer: __D, ) -> Result<NodeError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NodeError

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

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 JsonSchema for NodeError

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for NodeError

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
