Enum TraceContextError 

pub enum TraceContextError {
    InvalidFormat {
        field_count: usize,
    },
    InvalidTraceId {
        value: String,
    },
    InvalidSpanId {
        value: String,
    },
    ZeroTraceId,
    ZeroSpanId,
}

Errors that can occur when parsing a traceparent header.

Examples

use ironflow_core::trace_context::{WorkflowTraceContext, TraceContextError};

let err = WorkflowTraceContext::from_traceparent("bad").unwrap_err();
assert!(matches!(err, TraceContextError::InvalidFormat { .. }));

Variants

InvalidFormat

The header does not have the expected 4-field format.

Fields

field_count: usize

Number of fields found.

InvalidTraceId

The trace-id field is not valid lowercase hex of the expected length.

Fields

value: String

The raw value found.

InvalidSpanId

The span-id (parent-id) field is not valid lowercase hex of the expected length.

Fields

value: String

The raw value found.

ZeroTraceId

The trace-id is all zeros, which is invalid per the W3C spec.

ZeroSpanId

The span-id is all zeros, which is invalid per the W3C spec.

Trait Implementations

impl Debug for TraceContextError

impl Eq for TraceContextError

impl Error for TraceContextError

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 TraceContextError

fn eq(&self, other: &TraceContextError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
