Example of injecting a data section into an existing wasm module.
This repo shows how a wasm module can be created which uses static data that is expected to be added at a later time. There are two artifacts:
This is a wasm module which reads a passive data section into a vector. The passive data section is not actually present when the wasm module is built. Instead, it is expected that the additional data section be injected later.
This is a native binary that can mutate static-wasm to inject new data as an additional passive data segment.
The script test.sh shows how to build static-wasm, then use inject to add a data segment, and then run the resulting wasm with wasmtime.
