I just started learning Rust and tried to write make a simple HTTP request using reqwest
I tried to create a reqwest::Client, but VSCode didn't give me a corresponding completion.
But after I wrote the code myself, VSCode showed me that it knows the type of the expression.
And after I wrote let res = client., it still does not give me any completion about this.
Why can this happen?
I'm guessing you're using the Rust extension for VSCode instead of rust-analyzer. Both of these extensions provide a language server, which ultimately is what's responsible for code suggestions.
I ran into similar problems with subpar autocomplete when using VSCode with the Rust extension. Uninstalling that, and installing the rust-analyzer extension instead, resulted in a far superior experience. The rust-analyzer language server is now also officially recommended moving forwards, as stated here:
The RFC proposes a plan to adopt rust-analyzer as Rust's official LSP implementation.
where LSP is an acronym for Language Server Protocol.
