Trace Context parsing errors

Variants

InvalidFormat

Invalid format (must be version-trace_id-parent_id-flags)

InvalidVersion

Invalid version (must be 00)

InvalidTraceId

Invalid trace_id (must be 32 hex chars)

InvalidParentId

Invalid parent_id (must be 16 hex chars)

InvalidTraceFlags

Invalid trace_flags (must be 2 hex chars)

AllZeroTraceId

Trace ID is all zeros (forbidden by W3C spec)

AllZeroParentId

Parent ID is all zeros (forbidden by W3C spec)

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, f: &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.
