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"
