toml-rs VS rust-analyzer

I updated the toml<->json online converter after the ValueAfterTable error has been fixed with toml 0.6. Very nice to see progress on the toml and toml_edit crates.

use std::fs::File; use std::io::Write; use std::collections::BTreeMap as Map; use serde_derive::{Serialize, Deserialize}; #[derive(Debug)] #[derive(Serialize, Deserialize)] #[serde(tag = "type0")] enum FooBarTwo<'a> { FooBarOne { string1: &'a str }, } #[derive(Debug)] #[derive(Serialize, Deserialize)] #[serde(tag = "type1")] enum FooBarThree<'a> { FooBarFour { string2: &'a str }, } #[derive(Debug)] #[derive(Serialize, Deserialize)] struct FooBarFour<'a> { black: &'a str, #[serde(borrow)] green: FooBarTwo<'a>, #[serde(borrow)] blue: FooBarThree<'a>, } #[derive(Debug)] #[derive(Serialize, Deserialize)] struct FooBarFourList<'a> { // Uasing a Map to workaround a known bug (#303) when using top level Vec // see https://github.com/alexcrichton/toml-rs/issues/303 #[serde(borrow)] foo_bar_six: Map<&'a str, FooBarFour<'a>> } fn main() { let red = FooBarFour { black: "aaa", green: FooBarTwo::FooBarOne { string1: "aaaabbbb" }, blue: FooBarThree::FooBarFour { string2: "ccccccc" }, }; let pink = FooBarFour { black: "aaa", green: FooBarTwo::FooBarOne { string1: "aaaabbbb" }, blue: FooBarThree::FooBarFour { string2: "ccccccc" }, }; let mut white = Map::new(); white.insert("pink", pink); white.insert("red", red); let fbfl = FooBarFourList { foo_bar_six: white }; println!("\nTL: {:?}\n", fbfl); let filename = "./data/test.toml"; let data = toml::to_string(&fbfl).expect("Error serialising fbfl"); println!("\nTL as TOML: {:?}\n", data); let mut f = File::create(filename).expect("Unable to create file"); f.write_all(data.as_bytes()).expect("Error writing data to file"); let toml_in: FooBarFour = toml::from_str(&data).expect("Error deserialising fbfl"); println!("\n{:?}\n", toml_in); }

This is especially useful for data deserialization: Just by implementing the Serialize and Deserialize traits from the serde crate, the (almost) universally used serialization library in the Rust world, we can then serialize and deserialize our types to a lot of data formats: JSON, YAML, TOML, BSON and so on...

It looks like the fields are public now (https://github.com/alexcrichton/toml-rs/pull/455, https://docs.rs/toml/latest/toml/value/struct.Date.html), so just upgrading the crate should do it :-)

Pair that with Serde for serialization/deserialization (JSON, TOML, YAML, CSV/TSV, XML, URL query strings, etc.), Figment for configuration, and ignore for filesystem traversal with blacklist support, and Rust is a real joy for writing CLI utilities.

Added toml-rs-compatible API via the toml_edit::easy module for when developers want to ensure consistency between format-preserving and general TOML work, with one caveat.

A quick example off the top of the head of my head is some tests in the toml package. It has a few different approaches. One is to use macros as in parser.rs. In valid.rs and invalid.rs it uses macros to generate a separate test for each input file. This allows you to run just one individual test from the list. These examples aren't perfect, and there are more sophisticated test utilities (like insta) that can abstract the process of "here are a bunch of inputs, test them all".

I want to read a toml file with default value. I tried toml-rs but it doesn't allow for default values.

I would like changes like https://github.com/rust-analyzer/rust-analyzer/pull/13799 to be listed in 'Breaking Changes' category, to приманка draw the users' attention.

For those of you who haven’t heard of Mun before, Mun is an embeddable programming language empowering creation through iteration. The idea to create Mun originated out of frustration with the Lua dynamic scripting language and a desire to have similar hot reloading functionality available in Rust. As such, it’s not a direct competitor with Rust, but instead is intended to be used with Rust (or C/C++) as a host/embedded language pairing. Actually, Mun is completely written in Rust, building on similar crates as rust-analyzer and rustc. Its key features include:

#13728 upgrade chalk to make solver fuel work again (works around most trait solving hangs).

#13221 (first contribution) add option to move lenses above doc comments (rust-analyzer.lens.location):

Rust-analyzer has a good overview: https://github.com/rust-analyzer/rust-analyzer/blob/master/docs/dev/syntax.md

#12517 (first contribution) fix completion for methods in trait generated by macro.
