//! Custom logging macros, with the same names as `log` crate's `trace!`, `debug!`, `info!`, `warn!`, `error!`,
//! but different behavior: automatically prepend `file!()` information to the message.
//!
//! # Usage
//! ```ignore
//! trace!("value = {}", x);
//! debug!("something happened");
//! info!("user {} logged in", username);
//! warn!("disk space low: {} GB", free);
//! error!("failed to open file: {}", path);
//! ```
//!
//! Expands to:
//! ```ignore
//! ::log::trace!("[{}]: {}", file!(), format!("value = {}", x));
//! ::log::debug!("[{}]: {}", file!(), format!("something happened"));
//! ...
//! ```
#[macro_export]
macro_rules! trace {
($($arg:tt)*) => {
::log::trace!("[{}]: {}", file!(), format!($($arg)*));
};
}
#[macro_export]
macro_rules! debug {
($($arg:tt)*) => {
::log::debug!("[{}]: {}", file!(), format!($($arg)*));
};
}
#[macro_export]
macro_rules! info {
($($arg:tt)*) => {
::log::info!("[{}]: {}", file!(), format!($($arg)*));
};
}
#[macro_export]
macro_rules! warn {
($($arg:tt)*) => {
::log::warn!("[{}]: {}", file!(), format!($($arg)*));
};
}
#[macro_export]
macro_rules! error {
($($arg:tt)*) => {
::log::error!("[{}]: {}", file!(), format!($($arg)*));
};
}
