use actix web from other dependencies

[shishamo]

I would like to use actix web from a common dependency but i have an error as below
could not find "actix_web" in the list of imported crates
actix_web_codegen
proc_macro main

Here is my project tree

|-- common
| |-- src
| | |-- external_libs
| | | |-- mod.rs
| | |-- lib.rs
| |
| |-- cargo.toml
|
|
|-- project
| |-- app
| | |-- src
| | | |-- lib.rs
| | |-- cargo.toml
| |
| |-- api
| | |--cargo.toml

the mod.rs file in common external_libs dir

pub use actix_files;

the lib.rs file in common dir

mod external_libs;

pub use external_libs::*;

the cargo.toml file in common dir

[package]
name = "common"

[dependencies]
actix-web = "^4.3"

the cargo file in project dir

members = ["app/"]

the cargo file in project dir

[package]
name = "app"

[dependencies]
common = { path = "../../common/" }

and the lib.rs in app dir

use common::actix_web;

#[actix_web::main]
async fn main() -> Result<()> {
   ....
}

Rust analyzer can jump inside Actix web so looks like the dependency can be find but the compiler fails....

Could someone help me please? T_T

Macros can't resolve dependencies like this. You'll need to:

• avoid the attribute macro for this case
• use #[::common::actix_web::rt::main(system = "::common::actix_web::rt::System")]

thanks a lot @robjtede ^^

btw how can i use the #[actix_web::test] in that case?

[shishamo]

it looks like it is working in using as below
#[::static_common::actix_web::rt::test(system = "::static_common::actix_web::rt::System")]

[shishamo]

but i have another issue this the get attribute macro
#[get("/endpoint")]

@robjtede
how can i use it in that way?

The routing macros currently have no support for alternative crate paths. You'll have to use manual routing.

thanks a lot!
