Struct TraceparentCtxt

pub struct TraceparentCtxt<C = Empty> { /* private fields */ }

A Ctxt that synchronizes Traceparents with an underlying ambient context.

The trace context is shared by all instances of TraceparentCtxt, and any calls to Traceparent::current and Traceparent::push.

Implementations

impl<C> TraceparentCtxt<C>

pub const fn new(inner: C) -> Self

Wrap the given context, synchronizing any emit::SpanCtxt with the current Traceparent.
