Enum TraceContextError 

pub enum TraceContextError {
    InvalidFormat,
    UnsupportedVersion,
    ZeroTraceId,
    ZeroSpanId,
}

Error returned when parsing a traceparent header fails.

Variants

InvalidFormat

The overall format is wrong (wrong number of fields, wrong lengths, etc.).

UnsupportedVersion

The version byte is not supported (only 00 is currently valid).

ZeroTraceId

The trace-id field is all zeros, which the spec forbids.

ZeroSpanId

The span-id field is all zeros, which the spec forbids.

Trait Implementations

impl Clone for TraceContextError

fn clone(&self) -> TraceContextError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceContextError

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

Formats the value using the given formatter.

impl Display for TraceContextError

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

Formats the value using the given formatter.

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

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.
