pub fn trace_id(&self) -> Uuid

Returns the trace ID.

pub fn content_type(&self) -> &str

Returns the content type.

pub fn headers(&self) -> &[(SharedString, String)]

Returns the custom headers.

pub fn trace_context(&self) -> (String, String)

Returns the trace context in the form (traceparent, tracestate).

pub fn server_timing(&self) -> String

Returns the server timing.

pub fn read_bytes(&mut self) -> Result<Bytes, Error>
