Printers

Printers are host programs that receive log data, format it and display it. The following printers are currently available:

• probe-run, parses data sent over RTT (ARM Cortex-M only).

  💡 If you are using the git version of defmt, make sure you also install the tool from git and not crates.io.

• defmt-print, a generic command-line tool that decodes defmt data passed into its standard input.
• qemu-run, parses data sent by QEMU over semihosting (ARM Cortex-M only).

  💡 Used for internal testing and won't be published to crates.io
