Module warp::filters::trace

tracing filters.

tracing is a framework for instrumenting Rust programs to collect scoped, structured, and async-aware diagnostics. This module provides a set of filters for instrumenting Warp applications with tracing spans. Spans can be used to associate individual events with a request, and track contexts through the application.

Structs

• Info
  Information about the request/response that can be used to prepare log lines.
• Trace
  Decorates a Filter to create a tracing span for requests and responses.

Functions

• named
  Create a wrapping filter that instruments every request with a tracing Span at the DEBUG level representing a named context.
• request
  Create a wrapping filter that instruments every request with a tracing Span at the INFO level, containing a summary of the request. Additionally, if the DEBUG level is enabled, the span will contain an event recording the request’s headers.
• trace
  Create a wrapping filter that instruments every request with a custom tracing Span provided by a function.
