use std::sync::LazyLock;

pub static DATABASE_URL: LazyLock<String> = LazyLock::new(|| {
    dotenv::dotenv().ok();
    std::env::var("DATABASE_URI").unwrap()
});
pub static SECRET_KEY: LazyLock<String> = LazyLock::new(|| {
    dotenv::dotenv().ok();
    std::env::var("SUPER_SECRET_KEY").unwrap()
});

I wrote this code in my lib.rs file. While I am trying to debug this variable its showing uninit
Also how to do this with only one dotenv::dotenv().ok()

Make a struct with both your field, and then make a lazy lock with it, and then call dotenv one once and make the struct read both env vars. That takes care of the one call.

hey can you show it please?

a bit later

# fervent sapphire a bit later 
struct Foo {
  db: String,
  secret: String,
}
impl Foo {
  fn new() -> Self {
    dotenv::dotenv().ok();
    Self {
      db: std::env::var("DATABASE_URI").unwrap()
      secret: std::env::var("SUPER_SECRET_KEY").unwrap()
    }
  }
}
pub static FOO: LazyLock<Foo> = LazyLock::new(Foo::new);

is this correct?

fervent sapphire
#

the new function is correct, the field types arent, just make them String and then wrap the entire struct in lazylock

#

now it is yeah

what is it showing

wide geyser
#

while I am trying to debug

[src/main.rs:3:5] &restfullapi::CONFIG = LazyLock(
    <uninit>,
)
# 
#[allow(non_snake_case)]
#[derive(Debug)]
pub struct AppConfig {
    DATABASE_URI: String,
    SECRET_KEY: String,
}

impl AppConfig {
    pub fn new() -> Self {
        dotenv::dotenv().ok();
        Self {
            DATABASE_URI: std::env::var("DATABASE_URI").unwrap(),
            SECRET_KEY: std::env::var("SUPER_SECRET_KEY").unwrap(),
        }
    }
}

pub static CONFIG: LazyLock<AppConfig> = LazyLock::new(AppConfig::new);
