Crate bitwarden_ffi 

Utilities for FFI bindings (WASM, UniFFI).

Re-exports proc macros from bitwarden-ffi-macro, plus the wire traits. FromWasm and ToWasm explain how a type crosses the wasm ABI.

Modules

wire 🔒

How a type crosses the wasm ABI.

wire_macros 🔒

The impl_wire_* macros, which implement the wire traits.

Macros

impl_wire_object

Implements both traits for a type that crosses as itself: a #[wasm_bindgen] handle, an extern "C" type, or a primitive wasm_bindgen already understands.

impl_wire_string

Implements the traits for a type that crosses as a String, so a malformed string is a WireError::Parse rather than a throw from inside FromWasmAbi.

Enums

WireError

A value could not be converted across the wasm ABI.

Traits

FromWasm

A type that can be received from JavaScript, crossing the ABI as Self::Wire.

ToWasm

A type that can be handed to JavaScript, crossing the ABI as Self::Wire.

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))].
