Enum TraceContextError 

pub enum TraceContextError {
    InvalidTraceparent(&'static str),
}

Returned by TraceContext::new when the traceparent is not a well-formed W3C value.

Variants

InvalidTraceparent(&'static str)

The traceparent string did not match the version-trace_id-span_id-flags shape; the payload explains which field was wrong.
