Module tracing

Available on crate feature tracing only.

This module provides primitives to work with tracing and tracing-subscriber in Lambda functions.

The tracing and tracing-subscriber crates are re-exported so you don’t have to include them as direct dependencies in your projects.

Re-exports

pub use tracing_subscriber as subscriber;

Modules

Structs

Dispatch

Re-export the tracing crate to have access to tracing macros like info!, debug!, trace! and so on. Dispatch trace data to a Subscriber.

Event

Re-export the tracing crate to have access to tracing macros like info!, debug!, trace! and so on. Events represent single points in time where something occurred during the execution of a program.

Id
