A simple middleware for [`tide`](https://github.com/http-rs/tide) using the [`tracing`](https://github.com/tokio-rs/tracing) crate for logging.

## Why
[`tide`](https://github.com/http-rs/tide) uses [`log`](https://github.com/rust-lang/log) in its [default logging middleware](https://docs.rs/tide/latest/tide/log/struct.LogMiddleware.html).
When using [`tracing-log`](https://github.com/tokio-rs/tracing/tree/master/tracing-log) most of the information from tide is lost.
This crate provides a middleware that exposes all that information to [`tracing`](https://github.com/tokio-rs/tracing) directly while also improving the structure of the logs using [`span!`](https://docs.rs/tracing/latest/tracing/span/index.html).

`tide-tracing` uses [opentelemetry conventional trace field names](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/semantic_conventions/http.md#common-attributes) by default.
