There's quite a few panic implementations now, so I think it'd be useful to list them here. I'm not sure where exactly they should be put though, because some of them are platform-independent while others aren't. Personally I think these belong in their own section.

List of crates:

panic-halt: Halts the processor on panics
panic-abort: Causes an abort on panics (nightly-only)
panic-ramdump: Writes the panic message into the beginning of RAM and enters an infinite loop; the message can be extracted by attaching a debugger (Cortex-M only)
panic-semihosting: Prints the panic message via semihosting to an attached debugger (Cortex-M only)
panic-itm: Prints the panic through the chip's ITM to a debugger attached to the SWO pin (Cortex-M with ITM only)

Maybe these deserve to be in the panic-section too:

@Disasm commented on GitHub (May 7, 2019): Maybe these deserve to be in the panic-section too: * [`no-panic`](https://crates.io/crates/no-panic) * [`dont_panic`](https://crates.io/crates/dont_panic) + [`dont_panic_slice`](https://crates.io/crates/dont_panic_slice)
