Therefore, add all of them to the prelude. For instance, this allows to write `Err(EINVAL)` to create a kernel `Result`: fn f() -> Result<...> { ... Err(EINVAL) } Signed-off-by: Wedson Almeida Filho Reviewed-by: Gary Guo [Reworded, adapted for upstream and applied latest changes] Signed-off-by: Miguel Ojeda --- rust/kernel/prelude.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/rust/kernel/prelude.rs b/rust/kernel/prelude.rs index 7c4c35bf3c66..1e08b08e9420 100644 --- a/rust/kernel/prelude.rs +++ b/rust/kernel/prelude.rs @@ -19,6 +19,6 @@ pub use macros::{module, vtable}; pub use super::{pr_alert, pr_crit, pr_debug, pr_emerg, pr_err, pr_info, pr_notice, pr_warn}; -pub use super::error::{Error, Result}; +pub use super::error::{code::*, Error, Result}; pub use super::ThisModule; -- 2.38.1
