How to import crates properly?

help
1

This is my very project using Rust where I want to use "windows" crate

[package]
name = "capture"
version = "0.1.0"
edition = "2021"

[dependencies]
windows = { version = "0.59.0", features = ["Win32_Graphics_Dxgi"]}


use windows::Win32::Graphics::Dxgi;

fn main() {
    println!("Hello, world!");
}

error[E0433]: failed to resolve: could not find `Win32` in `windows`
 --> src/main.rs:1:14
  |
1 | use windows::Win32::Graphics::Dxgi;
  |              ^^^^^ could not find `Win32` in `windows`

For more information about this error, try `rustc --explain E0433`.

Can someone tell what I am doing is it fundamentally wrong or is this something specific I use WSL2 for development

can you double check the features are enabled correctly? e.g. what's the output of:

$ cargo tree --format "{p} - {f}"
3 
cargo tree --format "{p} - {f}"
capture v0.1.0 (/mnt/d/Rust/capture) -

    │   │   │   └── unicode-ident v1.0.14 -
    │   │   ├── quote v1.0.38 - default,proc-macro
    │   │   │   └── proc-macro2 v1.0.92 - default,proc-macro (*)
    │   │   └── syn v2.0.95 - clone-impls,derive,full,parsing,printing,proc-macro

    │   │       ├── quote v1.0.38 - default,proc-macro (*)
    │   │       └── unicode-ident v1.0.14 -
    │   ├── windows-interface v0.59.0 (proc-macro) -
    │   │   ├── proc-macro2 v1.0.92 - default,proc-macro (*)
    │   │   ├── quote v1.0.38 - default,proc-macro (*)
    │   │   └── syn v2.0.95 - clone-impls,derive,full,parsing,printing,proc-macro (*)
    │   ├── windows-result v0.3.0 - std
    │   │   └── windows-targets v0.53.0 -
    │   │       └── windows_x86_64_gnu v0.53.0 -
    │   ├── windows-strings v0.3.0 - std

    │   └── windows-targets v0.53.0 -  (*)
    └── windows-targets v0.53.0 -  (*)

This is the result I don't quite get it, but I think imports are correct even after this is still showing the not found error

the features are enabled, all looks good to me, I don't know why you can the error.

btw, what's the full error message, if you use --verbose flag for cargo? e.g.:

$ cargo build -vvv

Are you trying this in some non-Windows environment? If yes, you need to explicitly use correct target, i.e. rustup target add x86_64-pc-windows-gnu and then cargo build --target=x86_64-pc-windows-gnu.

Yes I do use WSL2 (windows subsystem linux) for development, I used the commands that you gave.

Now it's working thanks for your help @Cerber-Ursi and @nerditation
