Struct TracingLayer 

pub struct TracingLayer { /* private fields */ }

Middleware layer that creates tracing spans for requests

This layer creates a span for each request containing:

• HTTP method
• Request path
• Request ID (if RequestIdLayer is applied)
• Response status code
• Request duration
• Any custom fields configured via with_field()

Example

use rustapi_core::middleware::TracingLayer;

RustApi::new()
    .layer(TracingLayer::new()
        .with_field("service", "my-api")
        .with_field("version", "1.0.0"))
    .route("/", get(handler))

Implementations

impl TracingLayer

pub fn new() -> Self

Create a new TracingLayer with default INFO level

pub fn with_level(level: Level) -> Self

Create a TracingLayer with a specific log level

pub fn with_field( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Add a custom field to all request spans

Custom fields are included in every span created by this layer.

Example

TracingLayer::new()
    .with_field("service", "my-api")
    .with_field("environment", "production")
