A Cli Example for Rust and WebAssembly Hostcall

Usage

# build wasms for ervery module in the `wasm` directory and move them to the root directory
# example:
cd wasm/module_A
cargo build --target wasm32-wasi --release

cp target/wasm32-wasi/release/module_A.wasm ../../

# build and run the Cli
cd ../../src
cargo run

Add new wasm modules

Just follow what was done in module_A.

demostrate how hot-update works

load module_A.wasm A

output:
    Loading module from module_A.wasm
    load module module_A.wasm success, and registry as A

call A modulef1 {"message":"hello_from_cli"}

output:
    Calling function modulef1 in module A with param {"message":"hello_from_cli"}
    enter module a, message: "hello_from_cli"
    enter host f1, message: "implemented in host"

load module_B.wasm A

output:
    Loading module from module_B.wasm
    load module module_B.wasm success, and registry as A

call A modulef1 {"message":"hello_from_cli"}

output:
    Calling function modulef1 in module A with param {"message":"hello_from_cli"}
    enter module b, message: "hello_from_cli"
    enter host f1, message: "implemented in host"

with test

output:
    call from test thread
    module or function not found
    load module_B.wasm A
    Loading module from module_B.wasm
    module or function not found
    load module module_B.wasm success, and registry as A
    enter module b, message: "hello_from_cli"
    enter host f1, message: "implemented in host"

    enter module b, message: "hello_from_cli"
    enter host f1, message: "implemented in host"

    enter module b, message: "hello_from_cli"
    enter host f1, message: "implemented in host"
