Function uniffi::uniffi_rustbuffer_alloc

pub fn uniffi_rustbuffer_alloc(
    size: u64,
    call_status: &mut RustCallStatus
) -> RustBuffer

This helper allocates a new byte buffer owned by the Rust code, and returns it to the foreign-language code as a RustBuffer struct. Callers must eventually free the resulting buffer, either by explicitly calling uniffi_rustbuffer_free defined below, or by passing ownership of the buffer back into Rust code.
