Macro std::panic 1.0.0
[−]
[src]
macro_rules! panic { () => { ... }; ($msg:expr) => { ... }; ($fmt:expr, $($arg:tt)+) => { ... }; }
The entry point for panic of Rust threads.
This macro is used to inject panic into a Rust thread, causing the thread to
panic entirely. Each thread's panic can be reaped as the Box<Any>
type,
and the single-argument form of the panic!
macro will be the value which
is transmitted.
The multi-argument form of this macro panics with a string and has the
format!
syntax for building a string.
Current implementation
If the main thread panics it will terminate all your threads and end your
program with code 101
.
Examples
panic!(); panic!("this is a terrible mistake!"); panic!(4); // panic with the value of 4 to be collected elsewhere panic!("this is a {} {message}", "fancy", message = "message");Run
