Library setup
If your library will use any of the logging macros (trace!
, debug!
, info!
, warn!
, error!
) then you'll need to add these Cargo features to your library's Cargo.toml
:
# under the features section, copy these
[features]
# ↓↓↓↓↓
defmt-default = []
defmt-trace = []
defmt-debug = []
defmt-info = []
defmt-warn = []
defmt-error = []
# ↑↑↑↑↑
You do not need to add these features if you are only going to use the #[derive(Format)]
attribute.
