The documentation -//! comments ``/// something`` (as well as other meta attrbiutes) on variants -//! are allowed. -//! -//! # Allowed Syntax -//! -//! You may add arbitrary parameters to any struct variant: -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! /// IO Error -//! Io(err: std::io::Error) {} -//! /// Utf8 Error -//! Utf8(err: std::str::Utf8Error) {} -//! } -//! } -//! ``` -//! -//! Note unlike in normal Enum declarations you declare names of fields (which -//! are omitted from type). How they can be used is outlined below. -//! -//! Now you might have noticed trailing braces `{}`. They are used to define -//! implementations. By default: -//! -//! * `Error::cause()` returns None (even if type wraps some value) -//! * `Display` outputs debug representation -//! * No `From` implementations are defined -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! Io(err: std::io::Error) { -//! display("{}", err) -//! } -//! Utf8(err: std::str::Utf8Error) { -//! display("utf8 error") -//! } -//! } -//! } -//! ``` -//! -//! To change `cause` method to return some error, add `cause(value)`, for -//! example: -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! Io(err: std::io::Error) { -//! cause(err) -//! } -//! Utf8(err: std::str::Utf8Error) { -//! display("utf8 error") -//! } -//! Other(err: Box<std::error::Error>) { -//! cause(&**err) -//! } -//! } -//! } -//! ``` -//! Note you don't need to wrap value in `Some`, its implicit. In case you want -//! `None` returned just omit the `cause`. You can't return `None` -//! conditionally. -//! -//! To change how each clause is `Display`ed add `display(pattern,..args)`, -//! for example: -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! Io(err: std::io::Error) { -//! display("I/O error: {}", err) -//! } -//! Utf8(err: std::str::Utf8Error) { -//! display("Utf8 error, valid up to {}", err.valid_up_to()) -//! } -//! } -//! } -//! ``` -//! -//! If you need a reference to the error when `Display`ing, you can instead use -//! `display(x) -> (pattern, ..args)`, where `x` sets the name of the reference. -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! use std::error::Error; // put methods like `source()` of this trait into scope -//! -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! Io(err: std::io::Error) { -//! display(x) -> ("I/O: {}", err) -//! } -//! Utf8(err: std::str::Utf8Error) { -//! display(self_) -> ("UTF-8 error. Valid up to {}", err.valid_up_to()) -//! } -//! } -//! } -//! ``` -//! -//! To convert to the type from any other, use one of the three forms of -//! `from` clause. -//! -//! For example, to convert simple wrapper use bare `from()`: -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! Io(err: std::io::Error) { -//! from() -//! } -//! } -//! } -//! ``` -//! -//! This implements ``From<io::Error>``. -//! -//! To convert to singleton enumeration type (discarding the value), use -//! the `from(type)` form: -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! FormatError { -//! from(std::fmt::Error) -//! } -//! } -//! } -//! ``` -//! -//! And the most powerful form is `from(var: type) -> (arguments...)`. It -//! might be used to convert to type with multiple arguments or for arbitrary -//! value conversions: -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # fn main() {} -//! # -//! quick_error! { -//! #[derive(Debug)] -//! pub enum SomeError { -//! FailedOperation(s: &'static str, errno: i32) { -//! from(errno: i32) -> ("os error", errno) -//! from(e: std::io::Error) -> ("io error", e.raw_os_error().unwrap()) -//! } -//! /// Converts from both kinds of utf8 errors -//! Utf8(err: std::str::Utf8Error) { -//! from() -//! from(err: std::string::FromUtf8Error) -> (err.utf8_error()) -//! } -//! } -//! } -//! ``` -//! # Context -//! -//! Since quick-error 1.1 we also have a `context` declaration, which is -//! similar to (the longest form of) `from`, but allows adding some context to -//! the error. We need a longer example to demonstrate this: -//! -//! ```rust -//! # #[macro_use] extern crate quick_error; -//! # use std::io; -//! # use std::fs::File; -//! # use std::path::{Path, PathBuf}; -//! # -//! use quick_error::ResultExt; -//! -//! quick_error! { -//! #[derive(Debug)] -//! pub enum Error { -//! File(filename: PathBuf, err: io::Error) { -//! context(path: &'a Path, err: io::Error) -//! -> (path.to_path_buf(), err) -//! } -//! } -//! } -//! -//! fn openfile(path: &Path) -> Result<(), Error> { -//! try!(File::open(path).context(path)); -//! -//! // If we didn't have context, the line above would be written as; -//! // -//! // try!(File::open(path) -//! // .map_err(|err| Error::File(path.to_path_buf(), err))); -//! -//! Ok(()) -//! } -//! -//! # fn main() { -//! # openfile(Path::new("/etc/somefile")).ok(); -//! # } -//! ``` -//! -//! Each `context(a: A, b: B)` clause implements -//! `From<Context<A, B>> for Error`. Which means multiple `context` clauses -//! are a subject to the normal coherence rules. Unfortunately, we can't -//! provide full support of generics for the context, but you may either use a -//! lifetime `'a` for references or `AsRef<Type>` (the latter means `A: -//! AsRef<Type>`, and `Type` must be concrete). It's also occasionally useful -//! to use a tuple as a type of the first argument. -//! -//! You also need to `use quick_error::ResultExt` extension trait to get -//! working `.context()` method. -//! -//! More info on context in [this article](http://bit.ly/1PsuxDt). -//! -//! All forms of `from`, `display`, `cause`, and `context` -//! clauses can be combined and put in arbitrary order. Only `from` and -//! `context` can be used multiple times in single variant of enumeration. -//! Docstrings are also okay. Empty braces can be omitted as of quick_error -//! 0.1.3. -//! -//! # Private Enums -//! -//! Since quick-error 1.2.0 we have a way to make a private enum that is -//! wrapped by public structure: -//! -//! ```rust -//! #[macro_use] extern crate quick_error; -//! # fn main() {} -//! -//! quick_error! { -//! #[derive(Debug)] -//! pub enum PubError wraps ErrorEnum { -//! Variant1 {} -//! } -//! } -//! ``` -//! -//! This generates data structures like this -//! -//! ```rust -//! -//! pub struct PubError(ErrorEnum); -//! -//! enum ErrorEnum { -//! Variant1, -//! } -//! -//! ``` -//! -//! Which in turn allows you to export just `PubError` in your crate and keep -//! actual enumeration private to the crate. This is useful to keep backwards -//! compatibility for error types. Currently there is no shorcuts to define -//! error constructors for the inner type, but we consider adding some in -//! future versions. -//! -//! It's possible to declare internal enum as public too. -//! -//! - - -/// Main macro that does all the work -#[macro_export] -macro_rules! quick_error { - - ( $(#[$meta:meta])* - pub enum $name:ident { $($chunks:tt)* } - ) => { - quick_error!(SORT [pub enum $name $(#[$meta])* ] - items [] buf [] - queue [ $($chunks)* ]);
