Rust and blink.cmp

Im trying to setup rust autocompletion with blink.cmp, i have nvim-lspconfig,mason-lspconfig,mason-tool-installer, blink.cmp, luasnip, lazydev and rustaceanvim setup, mason-lspconfig has auto enable on, blink uses basically the default, signatures are enabled and lazydev is also setup.
Lua_ls and clangd work with no issues but for rust-analyzer the popupmenu doesnt even appear.
I tried changing up my sources, disabeling auto setup, manually enabeling the lsp, tried bacon-ls and tried rust.vim, not autocompletion, autoformatting works tho.
How can i fix that?

Edit: It kind of fixed itself, dont know what i did, installed and reinstalled rustaceanvim and rust-analyzer multiple times, even made a completely new nvim config only with nvim-lspconfig,blink and rustaceanvim to see if its some specific plugin or config which caused the issues but now it works, thanks for the tips, im only gonna install rust-analyzer from rustup now
