HTTP Example

This is a simple example using hyper that demonstrates tracing http request from client to server. The example shows key aspects of tracing such as:

Root Span (on Client)
Child Span from a Remote Parent (on Server)
Child Span created on the async function parented by the first level child (on Server)
SpanContext Propagation (from Client to Server)
Span Events
Span Attributes
Context propagation across async task boundaries.

Usage

# Run server
$ cargo run --bin http-server

# In another tab, run client
$ cargo run --bin http-client

# The spans should be visible in stdout in the order that they were exported.
