From fc6c6baa1f40ded13e539d0c1a17bcefc00abad9 Mon Sep 17 00:00:00 2001 From: Benno Lossin Date: Sat, 8 Apr 2023 12:25:51 +0000 Subject: rust: init: add initialization macros Add the following initializer macros: - `#[pin_data]` to annotate structurally pinned fields of structs, needed for `pin_init!` and `try_pin_init!` to select the correct initializer of fields. - `pin_init!` create a pin-initializer for a struct with the `Infallible` error type. - `try_pin_init!` create a pin-initializer for a struct with a custom error type (`kernel::error::Error` is the default). - `init!` create an in-place-initializer for a struct with the `Infallible` error type. - `try_init!` create an in-place-initializer for a struct with a custom error type (`kernel::error::Error` is the default). Also add their needed internal helper traits and structs.
