2834: refactor(ra_syntax.validation): removed code duplication from validate_literal() r=kiljacken a=Veetaha Hi! This is my first ever contribution to this project. I've taken some dirty job from issue #223 This is a simple atomic PR to remove code duplication according to FIXME comment in the function that is the main focus of the further development. I just didn't want to mix refactoring with the implementation of new features... I am not sure whether you prefer such atomic PRs here or you'd rather have a single PR that contains all atomic commits inside of it? So if you want me to add all that validation in one PR I'll mark this one as WIP and update it when the work is finished, otherwise, I'll go with the option of creating separate PRs per each feature of validation of strings, numbers, and comments respectively. ### Comments about refactoring Yeah, reducing the duplication is quite hard here, extracting into stateless functions could be another option but the number of their arguments would be very big and repeated across char and string implementations so that just writing their types and names would become cumbersome. I tried the option of having everything captured implicitly in the closure but failed since rust doesn't have templated (or generic) closures as C++ does, this is needed because `unescape_byte*()` and `unescape_char|str()` have different return types... Maybe I am missing something here? I may be wrong because I am not enough experienced in Rust... Well, I am awaiting any kind of feedback! Co-authored-by: Veetaha <gerzoh1@gmail.com> |

Rust Analyzer
Rust Analyzer is an experimental modular compiler frontend for the Rust language. It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust. If you want to get involved, check the rls-2.0 working group in the compiler-team repository:
https://github.com/rust-lang/compiler-team/tree/master/content/working-groups/rls-2.0
Work on the Rust Analyzer is sponsored by
Language Server Quick Start
Rust Analyzer is a work-in-progress, so you'll have to build it from source, and you might encounter critical bugs. That said, it is complete enough to provide a useful IDE experience and some people use it as a daily driver.
To build rust-analyzer, you need:
- latest stable rust for language server itself
- latest stable npm and VS Code for VS Code extension
To quickly install rust-analyzer with VS Code extension with standard setup
(code and cargo in $PATH, etc), use this:
# clone the repo
$ git clone https://github.com/rust-analyzer/rust-analyzer && cd rust-analyzer
# install both the language server and VS Code extension
$ cargo xtask install
# alternatively, install only the server. Binary name is `ra_lsp_server`.
$ cargo xtask install --server
For non-standard setup of VS Code and other editors, or if the language server cannot start, see ./docs/user.
Documentation
If you want to contribute to rust-analyzer or just curious about how things work under the hood, check the ./docs/dev folder.
If you want to use rust-analyzer's language server with your editor of choice, check ./docs/user folder. It also contains some tips & tricks to help you be more productive when using rust-analyzer.
