Multi-line + comments using `///` are otherwise treated as an error, so use this + attribute or consider switching to block doc comments (`/** */`). + + - `#[prefix_enum_doc_attributes]` combines the doc comment message on + your enum itself with the messages for each variant, in the format + “enum: variant”. When added to an enum, the doc comment on the enum + becomes mandatory. When added to any other type, it has no effect. + +- In case you want to have an independent doc comment, the + `#[displaydoc("...")` atrribute may be used on the variant or struct to + override it. + +
+ +### FAQ + +1. **Is this crate `no_std` compatible?** + * Yes! This crate implements the `core::fmt::Display` trait not the `std::fmt::Display` trait so it should work in `std` and `no_std` environments. Just add `default-features = false`. + +2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** + * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl, it then specializes for `Path` and `PathBuf` and when either of these types are found it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the Display format specifier! + + +#### License + + +Licensed under either of Apache License, Version +2.0 or MIT license at your option. + + +

+//! +//! ## Details +//! +//! - A `Display` impl is generated for your type if you provide doc comment +//! messages on the struct or each variant of your enum, as shown above in the +//! example. +//! +//! The messages support a shorthand for interpolating fields from the error. +//! +//! - `/// {var}` ⟶ `write!("{}", self.var)` +//! - `/// {0}` ⟶ `write!("{}", self.0)` +//! - `/// {var:?}` ⟶ `write!("{:?}", self.var)` +//! - `/// {0:?}` ⟶ `write!("{:?}", self.0)` +//! +//! - Two optional attributes can be added to your types next to the derive: +//! +//! - `#[ignore_extra_doc_attributes]` makes the macro ignore any doc +//! comment attributes (or `///` lines) after the first. Multi-line +//! comments using `///` are otherwise treated as an error, so use this +//! attribute or consider switching to block doc comments (`/** */`). +//! +//! - `#[prefix_enum_doc_attributes]` combines the doc comment message on +//! your enum itself with the messages for each variant, in the format +//! “enum: variant”. When added to an enum, the doc comment on the enum +//! becomes mandatory. When added to any other type, it has no effect. +//! +//! - In case you want to have an independent doc comment, the +//! `#[displaydoc("...")` atrribute may be used on the variant or struct to +//! override it. +//! +//!

This crate implements the `core::fmt::Display` trait not the `std::fmt::Display` trait so it should work in `std` and `no_std` environments. Just add `default-features = false`. +//! +//! 2. **Does this crate work with `Path` and `PathBuf` via the `Display` trait?** +//! * Yuuup. This crate uses @dtolnay's [autoref specialization technique](https://github.com/dtolnay/case-studies/blob/master/autoref-specialization/README.md) to add a special trait for types to get the display impl, it then specializes for `Path` and `PathBuf` and when either of these types are found it calls `self.display()` to get a `std::path::Display<'_>` type which can be used with the Display format specifier! +#![doc(html_root_url = "https://docs.rs/displaydoc/0.2.3")] +#![cfg_attr(docsrs, feature(doc_cfg))] +#![warn( + rust_2018_idioms, + unreachable_pub, + bad_style, + const_err, + dead_code, + improper_ctypes, + non_shorthand_field_patterns, + no_mangle_generic_items, + overflowing_literals, + path_statements, + patterns_in_fns_without_body, + private_in_public, + unconditional_recursion, + unused, + unused_allocation, + unused_comparisons, + unused_parens, + while_true +)] +#![allow(clippy::try_err)] + +#[allow(unused_extern_crates)] +extern crate proc_macro; + +mod attr; +mod expand; +mod fmt; + +use proc_macro::TokenStream; +use syn::{parse_macro_input, DeriveInput}; + +/// Derive macro for implementing `Display` via doc comment attributes +#[proc_macro_derive( + Display, + attributes(ignore_extra_doc_attributes, prefix_enum_doc_attributes, displaydoc) +)] +pub fn derive_error(input: TokenStream) -> TokenStream { + let input = parse_macro_input!(input as DeriveInput); + expand::derive(&input) + .unwrap_or_else(|err| err.to_compile_error()) + .into() +} diff --git a/vendor/displaydoc/tests/compile_tests.rs b/vendor/displaydoc/tests/compile_tests.rs new file mode 100644 index 000000000..29c72a862 --- /dev/null +++ b/vendor/displaydoc/tests/compile_tests.rs @@ -0,0 +1,29 @@ +#[allow(unused_attributes)] +#[rustversion::attr(not(nightly), ignore)] +#[test] +fn no_std() { + let t = trybuild::TestCases::new(); + #[cfg(not(feature = "std"))] + t.compile_fail("tests/no_std/without.rs"); + #[cfg(not(feature = "std"))] + t.compile_fail("tests/no_std/multi_line.rs"); + #[cfg(not(feature = "std"))] + t.pass("tests/no_std/multi_line_allow.rs"); + #[cfg(not(feature = "std"))] + t.compile_fail("tests/no_std/enum_prefix_missing.rs"); + #[cfg(not(feature = "std"))] + t.pass("tests/no_std/enum_prefix.rs"); + #[cfg(feature = "std")] + t.compile_fail("tests/std/without.rs"); + #[cfg(feature = "std")] + t.compile_fail("tests/std/multi_line.rs"); + #[cfg(feature = "std")] + t.pass("tests/std/multi_line_allow.rs"); + #[cfg(feature = "std")] + t.compile_fail("tests/std/enum_prefix_missing.rs"); + #[cfg(feature = "std")] + t.pass("tests/std/enum_prefix.rs"); + #[cfg(feature = "std")] + t.pass("tests/std/multiple.rs"); + t.pass("tests/no_std/with.rs"); +} diff --git a/vendor/displaydoc/tests/happy.rs b/vendor/displaydoc/tests/happy.rs new file mode 100644 index 000000000..85aa78f13 --- /dev/null +++ b/vendor/displaydoc/tests/happy.rs @@ -0,0 +1,152 @@ +use displaydoc::Display; + +#[cfg(feature = "std")] +use std::path::PathBuf; + +#[derive(Display)] +/// Just a basic struct {thing} +struct HappyStruct { + thing: &'static str, +} + +#[derive(Display)] +#[ignore_extra_doc_attributes] +/// Just a basic struct {thing} +/// and this line should get ignored +struct HappyStruct2 { + thing: &'static str, +} + +#[derive(Display)] +enum Happy { + /// I really like Variant1 + Variant1, + /// Variant2 is pretty swell 2 + Variant2, + /// Variant3 is okay {sometimes} + Variant3 { sometimes: &'static str }, + /** + * Variant4 wants to have a lot of lines + * + * Lets see how this works out for it + */ + Variant4, + /// Variant5 has a parameter {0} and some regular comments + // A regular comment that won't get picked + Variant5(u32), + + /// The path {0} + #[cfg(feature = "std")] + Variant6(PathBuf), + + /// These docs are ignored + #[displaydoc("Variant7 has a parameter {0} and uses #[displaydoc]")] + /// These docs are also ignored + Variant7(u32), +} + +// Used for testing indented doc comments +mod inner_mod { + use super::Display; + + #[derive(Display)] + pub enum InnerHappy { + /// I really like Variant1 + Variant1, + /// Variant2 is pretty swell 2 + Variant2, + /// Variant3 is okay {sometimes} + Variant3 { sometimes: &'static str }, + /** + * Variant4 wants to have a lot of lines + * + * Lets see how this works out for it + */ + Variant4, + /// Variant5 has a parameter {0} and some regular comments + // A regular comment that won't get picked + Variant5(u32), + + /** what happens if we + * put text on the first line?
