Both implementations call -/// `panic!` when they are set to [`None`] or [`Err`] variants. -/// -/// When using `panic!()` you can specify a string payload, that is built using -/// the [`format!`] syntax. That payload is used when injecting the panic into -/// the calling Rust thread, causing the thread to panic entirely. -/// -/// The behavior of the default `std` hook, i.e. the code that runs directly -/// after the panic is invoked, is to print the message payload to -/// `stderr` along with the file/line/column information of the `panic!()` -/// call. You can override the panic hook using [`std::panic::set_hook()`]. -/// Inside the hook a panic can be accessed as a `&dyn Any + Send`, -/// which contains either a `&str` or `String` for regular `panic!()` invocations. -/// To panic with a value of another other type, [`panic_any`] can be used. -/// -/// See also the macro [`compile_error!`], for raising errors during compilation. -/// -/// # When to use `panic!` vs `Result` -/// -/// The Rust language provides two complementary systems for constructing / -/// representing, reporting, propagating, reacting to, and discarding errors. These -/// responsibilities are collectively known as "error handling." `panic!` and -/// `Result` are similar in that they are each the primary interface of their -/// respective error handling systems; however, the meaning these interfaces attach -/// to their errors and the responsibilities they fulfill within their respective -/// error handling systems differ. -/// -/// The `panic!` macro is used to construct errors that represent a bug that has -/// been detected in your program. With `panic!` you provide a message that -/// describes the bug and the language then constructs an error with that message, -/// reports it, and propagates it for you. -/// -/// `Result` on the other hand is used to wrap other types that represent either -/// the successful result of some computation, `Ok(T)`, or error types that -/// represent an anticipated runtime failure mode of that computation, `Err(E)`. -/// `Result` is used alongside user defined types which represent the various -/// anticipated runtime failure modes that the associated computation could -/// encounter. `Result` must be propagated manually, often with the the help of the -/// `?` operator and `Try` trait, and they must be reported manually, often with -/// the help of the `Error` trait. -/// -/// For more detailed information about error handling check out the [book] or the -/// [`std::result`] module docs. -/// -/// [ounwrap]: Option::unwrap -/// [runwrap]: Result::unwrap -/// [`std::panic::set_hook()`]: ../std/panic/fn.set_hook.html -/// [`panic_any`]: ../std/panic/fn.panic_any.html -/// [`Box`]: ../std/boxed/struct.Box.html -/// [`Any`]: crate::any::Any -/// [`format!`]: ../std/macro.format.html -/// [book]: ../book/ch09-00-error-handling.html -/// [`std::result`]: ../std/result/index.html -/// -/// # Current implementation -/// -/// If the main thread panics it will terminate all your threads and end your -/// program with code `101`. -/// -/// # Examples -/// -/// ```should_panic -/// # #![allow(unreachable_code)] -/// use anstream::panic; -/// panic!(); -/// panic!("this is a terrible mistake!"); -/// panic!("this is a {} {message}", "fancy", message = "message"); -/// ``` -#[cfg(feature = "auto")] -#[macro_export] -macro_rules! panic { - () => { - ::std::panic!() - }; - ($($arg:tt)*) => {{ - use std::io::Write as _; - - let panic_stream = std::io::stderr(); - let choice = $crate::AutoStream::choice(&panic_stream); - let buffer = Vec::new(); - let mut stream = $crate::AutoStream::new(buffer, choice); - // Ignore errors rather than panic - let _ = ::std::write!(&mut stream, $($arg)*); - let buffer = stream.into_inner(); - // Should be UTF-8 but not wanting to panic - let buffer = String::from_utf8_lossy(&buffer).into_owned(); - ::std::panic!("{}", buffer) - }}; -} -- cgit v1.2.3
