# tracing-samply
A [`tracing-subscriber`] layer that bridges [`tracing`] with [`samply`].
Currently, this only records spans as markers using `samply`'s ad-hoc marker file format,
which are then detected at runtime by `samply` and written to the profile.
Markers for a thread are only detected if `samply` is attached when the thread is created.
This crate will adapt to any changes upstream.
The creator has expressed that the marker file is a temporary measure and that it will be replaced with a more robust solution in the future:

## Usage
```rust
use tracing_subscriber::prelude::*;
fn main() {
tracing_subscriber::registry()
// ... other layers
.with(tracing_samply::SamplyLayer::new().unwrap())
.init();
// Your application code that uses `tracing`
}
```
