native-1c

Создание компоненты с использованием native-1c

Более наглядно представлено в примере.

# Cargo.toml

[package]
name = "..."
version = "0.1.0"
edition = "2021"

[lib]
crate-type = ["cdylib"]

[dependencies]
native-1c = { git = "https://github.com/tuplecats/rust-native-1c.git" }

Для любой компоненты необходимо реализовать extern функции, которые использует 1С для подключения компоненты:

unsafe extern "C" fn GetClassObject(_name: *const u16, component: *mut *const u8) -> std::os::raw::c_long;
unsafe extern "C" fn DestroyObject(_component: *mut *const u8) -> std::os::raw::c_long;
unsafe extern "C" fn GetClassNames() -> *const u16;
unsafe extern "C" fn SetPlatformCapabilities(capabilities: AppCapabilities) -> AppCapabilities;

Любая структура, которая будет использоваться 1С, должна использовать процедурный макрос native_object, использовать #[repr(C)] и реализовывать трейт IComponentBase:

pub trait IComponentBase {
    // IInitDoneBaseVTable
    fn init(&mut self) -> bool;
    fn get_info(&self) -> i32;
    fn done(&mut self);

    // ILanguageExtenderBaseVTable
    fn get_n_props(&self) -> i32;
    fn find_prop(&self, prop_name: &str) -> i32;
    fn get_prop_name(&self, prop_num: i32, prop_alias: i32) -> &str;
    fn get_prop_val(&self, prop_num: i32, var_prop_val: &mut Variant) -> bool;
    fn set_prop_val(&mut self, prop_num: i32, var_prop_val: &Variant) -> bool;
    fn is_prop_readable(&self, prop_num: i32) -> bool;
    fn is_prop_writeable(&self, prop_num: i32) -> bool;
    fn get_n_methods(&self) -> i32;
    fn find_method(&self, method_name: &str) -> i32;
    fn get_method_name(&self, method_num: i32, method_alias: i32) -> &str;
    fn get_n_params(&self, method_num: i32) -> i32;
    fn get_param_def_value(&self, method_num: i32, param_num: i32, var_param_def_value: &mut Variant) -> bool;
    fn has_ret_val(&self, method_num: i32) -> bool;
    fn call_as_proc(&mut self, method_num: i32, params: Option<&mut [Variant]>) -> bool;
    fn call_as_func(&mut self, method_num: i32, ret_vals: &mut Variant, params: Option<&mut [Variant]>) -> bool;

    // LocaleBaseVTable
    fn set_locale(&mut self, loc: &str);
}
