Libraries

The CLI does not generate libraries yet (there is no library schematic and no import paths configured by the CLI).

Alternative: a library crate in the workspace

A Corvis module is a regular Rust type, so it can be published from any crate. Create a library crate in a Cargo workspace:

cargo new --lib libs/shared

# libs/shared/Cargo.toml
[dependencies]
corvis = { workspace = true }

// libs/shared/src/lib.rs
use corvis::prelude::*;

#[injectable]
pub struct ClockService;

impl ClockService {
    pub fn now_millis(&self) -> i64 {
        std::time::SystemTime::now()
            .duration_since(std::time::UNIX_EPOCH)
            .map(|d| d.as_millis() as i64)
            .unwrap_or(0)
    }
}

#[module(providers = [ClockService], exports = [ClockService])]
pub struct SharedModule;

And in the application:

# apps/api/Cargo.toml
[dependencies]
shared = { path = "../../libs/shared" }

#[module(imports = [shared::SharedModule], controllers = [AppController])]
pub struct AppModule;

The visibility rules are the usual ones: the application only sees what SharedModule exports. See Modules.

Corvis itself follows this pattern: corvis-orm is a separate crate that exposes OrmModule to import in any application.
