edwardium_logger 1.1.0

Simple logger implementation that works using targets.

Instead of needing multiple logging crates to log to multiple targets this crate provides a layer of abstraction and a few default targets. A target has to implement the Target trait.

This crate also has a no_std (disable default features) version and UART logging target using embedded-serial is provided under the uart_target feature.

To start logging, create the Logger object either statically or dynamically and then call one of its init_ methods.

For example, for a dynamic logger (requires std feature):

use edwardium_logger::targets::stderr::StderrTarget;
let logger = edwardium_logger::Logger::new(
[StderrTarget(log::Level::Trace)],
std::time::Instant::now()
);
logger.init_boxed().expect("Could not initialize logger");

Logger can also be created and set statically, though this has a few caveats (read the documentation of Logger::new for more):

use edwardium_logger::targets::stderr::StderrTarget;
use edwardium_logger::timing::DummyTiming;
static LOGGER: edwardium_logger::Logger<
StderrTarget,
[StderrTarget; 1],
DummyTiming
> = edwardium_logger::Logger {
targets: [StderrTarget::new(log::Level::Trace)],
start: DummyTiming,
ghost: std::marker::PhantomData
};
LOGGER.init_static();
