Module warp::filters::trace[−][src]

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.
