Loggerithm
Logging Library
Installation
# Cargo.toml
[dependencies]
loggerithm = "1"
static_init = "1.0.3"
Preparation
At the top of each module that logs text, you must add one of the following:
use loggerithm::logger;
// This will tell the module to use the logger from the parent module.
// If there is no parent module, it will use the default logger.
logger!(super);
use loggerithm::logger;
logger!(Logger::new()
// All of the settings here. See `src/logger.rs`.
);
Basic Logging
Loggerithm provides the standard logging levels, plus TRACE
NOTICE
SUCCESS
and FAILURE
.
The log!
macro is similar to the format!
macro, but takes a logging level as the first argument.
use loggerithm::level::{TRACE, DEBUG, INFO, NOTICE, SUCCESS, FAILURE, WARN, ERROR, FATAL};
use loggerithm::{log, logger};
logger!(super);
fn main() {
let x = 25;
log!(SUCCESS, "The value of x is equal to {}.", x);
}
See examples/basic_logging.rs
.
Custom Logging Levels
use loggerithm::{logger, log_level, log};
use loggerithm::level::INFO;
logger!(super);
log_level!(MY_AMAZING_CUSTOM_LOGGING_LEVEL, LogLevel::new(30)
.formatted(|v| v.magenta().on_white().reverse())
);
fn main() {
log!(INFO, "This example shows how to create a custom logging level and add formatting to it.");
log!(MY_AMAZING_CUSTOM_LOGGING_LEVEL, "This used my custom level, now with formatting!");
}
See examples/custom_level.rs
and examples/custom_level_formatting.rs
.
Custom Logger
use loggerithm::{logger, log};
use loggerithm::level::{INFO, WARN};
logger!(Logger::new()
.set_min_severity(WARN::severity())
.add_target(|context| {
println!("{} | {} | {}", context.time_local(), context.level_name_fp(), context.message())
})
);
fn main() {
log!(WARN, "This is logged.");
log!(INFO, "This is not logged because it is below the minimum severity.");
}
See examples/custom_logger.rs
