Research direction
Start by locating the book's existing logging guidance and check whether it discusses no_std environments or embedded handlers. Done means documenting that log works with no_std, can support RTT, semihosting, ITM, and UART, and explaining why supporting crates can defer output handling to the parent binary.
Written by the indexing model from the issue text.
Description
It would likely be good to point out in this book that log works in no_std environments, and can have handlers for RTT, semihosting, ITM, UART, etc.
Imho this is kind of important and isn't mentioned anywhere. It's much nicer for supporting crates to just use the log macro and allow the parent binary crate to determine how they should be printed.
