Crate bitwarden_ffi_macro 

Proc macros for FFI bindings (WASM, UniFFI).

Provides:

• #[wasm_export] attribute macro for an impl block or free function exported to JavaScript.
• #[wasm_record] attribute macro for a type that crosses the ABI through serde.
• #[wasm_object] attribute macro for a type that crosses the ABI as a handle.
• #[wasm_import] attribute macro for an extern "C" block of JavaScript imports.

Each macro replaces the attribute it stands in for rather than decorating it, so an item carries one of these and no #[wasm_bindgen] or #[tsify] of its own. That is what lets the expansion change without touching call sites.

An expansion names only bitwarden_ffi, so a call site imports nothing — but the crate has to forward its own wasm feature to bitwarden-ffi/wasm, which is where those names live.

Attribute Macros

wasm_export

Exports an impl block or a free function to JavaScript, in place of #[cfg_attr(feature = "wasm", wasm_bindgen(..))].

wasm_import

Declares a block of JavaScript imports, in place of #[wasm_bindgen] on an extern "C" block.

wasm_object

Declares a type that crosses the wasm ABI as an opaque handle, in place of #[cfg_attr(feature = "wasm", wasm_bindgen(..))] on a struct or an enum.

wasm_record

Declares a type that crosses the wasm ABI through serde, in place of #[cfg_attr(feature = "wasm", derive(Tsify), tsify(into_wasm_abi, from_wasm_abi))].
