The Rovella Logger
This is a simple low overhead logger than uses eprintln
and println
with format
to log text and other data.
Examples
The fatal macro is shown below and the other macros follow this pattern
macro_rules! log_fatal {
($($args:tt)*) => {
eprintln!("\x1b[1;92m{} \x1b[30;41m[FATAL]: {} \x1b[0m",
format!("[{}:{}]", file!(), line!()),
format!($($args)*),
);
};
}
The macro can be used just like println but it gives some extra info (along with color)
#[macro_use]
extern crate rovella_logger;
...
log_fatal!("Fatal error with code: {}", 4); // output => [src\main.rs:2] [FATAL]: Fatal error with code: 4
log_fatal!("Fatal"); // output => [src\main.rs:3] [FATAL]: Fatal
Macros with a security level below error don't compile to anything in release mode
#[macro_use]
extern crate rovella_logger;
...
log_warn!("I'm only in debug mode {}", 4); // output => ...
log_info!("I'm only in deubg mode"); // output => ...
