Macro errln::errln
[−]
[src]
macro_rules! errln { ($fmt:expr) => { ... }; ($fmt:expr, $($arg:tt)*) => { ... }; }
Macro for printing to the standard err, with a newline. On all
platforms, the newline is the LINE FEED character (\n
/U+000A
) alone
(no additional CARRIAGE RETURN (\r
/U+000D
).
Use the format!
syntax to write data to the standard output.
See std::fmt
for more information.
Panics
Panics if writing to io::stderr()
fails.
Examples
#[macro_use] extern crate errln; errln!("hello there!"); errln!("format {} arguments", "some");
