// the high level is we take a serde type, serialize it to a byte array,

// (we're doing this using bincode for now)
|
||||
// then toss that byte array into webassembly.
|
||||
// webassembly grabs that byte array, does some magic,
|
||||
// and serializes the result into yet another byte array.
|
||||
// we then grab *that* result byte array and deserialize it into a result.
|
||||
//
|
||||
// phew...
|
||||
//
|
||||
// now the problem is, webassambly doesn't support buffers.
|
||||
// only really like i32s, that's it (yeah, it's sad. Not even unsigned!)
|
||||
// (ok, I'm exaggerating a bit).
|
||||
//
|
||||
// the Wasm function that this calls must have a very specific signature:
|
||||
//
|
||||
// fn(pointer to byte array: i32, length of byte array: i32)
|
||||
// -> pointer to (
|
||||
// pointer to byte_array: i32,
|
||||
// length of byte array: i32,
|
||||
// ): i32
|
||||
//
|
||||
// This pair `(pointer to byte array, length of byte array)` is called a `Buffer`
|
||||
// and can be found in the cargo_test plugin.
|
||||
//
|
||||
// so on the wasm side, we grab the two parameters to the function,
|
||||
// stuff them into a `Buffer`,
|
||||
// and then pray to the `unsafe` Rust gods above that a valid byte array pops out.
|
||||
//
|
||||
// On the flip side, when returning from a wasm function,
|
||||
// we convert whatever serialized result we get into byte array,
|
||||
// which we stuff into a Buffer and allocate on the heap,
|
||||
// which pointer to we then return.
|
||||
// Note the double indirection!
|
||||
//
|
||||
// So when returning from a function, we actually leak memory *twice*:
|
||||
//
|
||||
// 1) once when we leak the byte array
|
||||
// 2) again when we leak the allocated `Buffer`
|
||||
//
|
||||
// This isn't a problem because Wasm stops executing after the function returns,
|
||||
// so the heap is still valid for our inspection when we want to pull things out.
