My Logger is a custom logging crate for Rust that provides a simple log! macro to log messages to a file with timestamps.
Add this crate to your Cargo.toml:
toml
[dependencies]
my_logger = "0.2.1" # Replace with the latest version available
First, import the log! macro from the crate:
rust
use my_logger::{log, logw, logd};
Then, you can use the log! macro to log messages:
rust
fn main() {
log!("This is a log message.");
log!("Another log message with a value: {}", 42);
let err = "Something went wrong!";
log!("error: {}", err);
logd!("debug: {}", err);
logw!("warning: {}", err);
}
The log messages will be written to a file named "file.log" in the current directory, and each log entry will include a timestamp.
The log file (file.log) will contain a line like this: ```log [2023-08-18 21:48:01] This is a log message. [2023-08-18 21:48:02] Another log message with a value: 42 [2023-08-18 21:48:03] error: Something went wrong! [2023-08-18 21:48:04] warning: Something went wrong! ``````
