Expand description

Represents an “extern C”-style function that will be part of the FFI.

These can’t be declared explicitly in the UDL, but rather, are derived automatically from the high-level interface. Each callable thing in the component API will have a corresponding FfiFunction through which it can be invoked, and UniFFI also provides some built-in FfiFunction helpers for use in the foreign language bindings.

Fields§

§name: String§is_async: bool§arguments: Vec<FfiArgument>§return_type: Option<FfiType>§has_rust_call_status_arg: bool§is_object_free_function: bool

Used by C# generator to differentiate the free function and call it with void* instead of C# SafeHandle type. See https://github.com/mozilla/uniffi-rs/pull/1488.
