defmt ("de format", short for "deferred formatting") is a highly efficient logging framework that targets resource-constrained devices, like microcontrollers. In its current iteration defmt mainly targets tiny embedded devices that have no means to display information to the developer, e.g. a screen. In this scenario, logs need to be transferred to a second machine, usually a PC/laptop, before they can be displayed to the developer/end-user.

Features

  • println!-like formatting
  • Multiple logging levels: error, info, warn, debug, trace
  • Compile-time RUST_LOG-like filtering of logs: include/omit logging levels with module-level granularity
  • Documentation available
  • Examples available
  • Timestamped logs
