Function init_observability 

pub fn init_observability(
    config: &ObservabilityConfig,
) -> Result<ObservabilityGuards>

Initialize all observability components

This is the recommended way to set up observability. It initializes:

• Logging (always)
• Metrics (always)
• Tracing (if enabled in config)

Returns guards that must be held for the lifetime of the application.

Example

use zlayer_observability::{init_observability, ObservabilityConfig};

#[tokio::main]
async fn main() {
    let config = ObservabilityConfig::default();
    let _guards = init_observability(&config).expect("Failed to init observability");

    tracing::info!("Application started");
    // guards are dropped when main exits, flushing logs and traces
}

Errors

Returns an error if any observability component fails to initialize.
