Enum TraceError 

pub enum TraceError {
    Length,
    Layout,
    NotHex,
    ForbiddenVersion,
    ZeroId,
}

Why a traceparent value was rejected.

Variants

Length

Not exactly 55 bytes (the only length defined for version 00).

Layout

Hyphens are not at offsets 2, 35 and 52.

NotHex

A field contained a byte that is not a lowercase hex digit.

ForbiddenVersion

Version ff is forbidden by the specification.

ZeroId

trace_id or span_id was all zero.

Trait Implementations

impl Clone for TraceError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TraceError

impl Debug for TraceError

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

impl Eq for TraceError

impl Error for TraceError

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 TraceError

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

Equality operator ==.

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

Inequality operator !=.
