In programming we use editors and IDEs all the time. Previously if one use Vi/Vim like text editor it typically means you just edit soruce code as simple text, but nowadays things have been changed. Especially after releasing support of the Language Server Protocol(LSP), which works as a client to LSP servers for example rust-analyzer. This talk gives deep dive of Language server Protocol implementation for Rust and how to build friendly relationships between rust-analyzer and Neovim. In this talk i’ll start from brief of what’s LSP and rust-analayzer, some missing features you probably didn’t know about? E.g. go-to-definition, find-references, hover, completion, rename, format, refactor, etc., using semantic whole-project analysis. Also i’ll show you how to write you first plugin using Rust and interact with some LSP primitives. to turn you editor in God mode surf trough it like a pro.
