rust-log-mdc

A mapped diagnostic context (MDC) for use with the log crate.

An MDC is a thread local map of strings used to make relevant information from a system available in its log messages. Logging crates such as log4rs will retrieve values from the MDC for output.

For example, a web server may process many requests simultaneously on different threads. Generating an ID for each request and storing it in the MDC makes it easy to partition log messages on a per-request basis.
