Viaduct.cpp 750
Viaduct.h Viaduct is a way for Application Services Rust components ( to make network requests using a trusted stack (gecko). The way it works is roughly as follows: - First we register a callback using `viaduct_initialize` (InitializeViaduct). This callback is stored on the Rust side in a static variable, therefore InitializeViaduct() must be called only once. - When the Rust code needs to make a network request, our callback (ViaductCallback) will be called with a protocol buffer describing the request to make on their behalf. Note 1: The callback MUST be called from a background thread as it is blocking. Note 2: It is our side responsibility to call `viaduct_destroy_bytebuffer` on the buffer. - We set a semaphore to make the background thread wait while we make the request on the main thread using nsIChannel. (ViaductRequest::MakeRequest) - Once a response is received, we allocate a bytebuffer to store the response using `viaduct_alloc_bytebuffer` and unlock the semaphore. (ViaductRequest::OnStopRequest) - The background thread is unlocked, and the callback returns the response to the Rust caller. (ViaductCallback) - The Rust caller will free the response buffer we allocated earlier. Reference: 1883
