Debug information is not included in build scripts by default anymore(속도 올리려고 1.69에서 디버그 정보 빠짐 다시 넣는 방법)|🔝|

• If you want to debug a build script, you can add this snippet to your Cargo.toml to emit debug information again:
• Cargo.toml https://blog.rust-lang.org/2023/04/20/Rust-1.69.0.html

[profile.dev.build-override]
debug = true
[profile.release.build-override]
debug = true

# Link-Time Optimizations, or LTOs in short, is that while Rust compiles the code file by file,
[profile.release]
lto = true

WASM 빌드하기(target add)|🔝|

rustup update
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

• https://stackoverflow.com/questions/66180416/rust-nightly-not-installed-please-install-it

• A simple main app(러스트 코드를 WASM 빌드하기_확장자명 .wasm)

• 여기에 정리중

  • The Hello World example is a standalone Rust application that can be executed by the WasmEdge CLI. The full source code for the Rust main.rs file is as follows. It echoes the command line arguments passed to this program at runtime.

fn main() {
  let s : &str = "Hello WasmEdge!";
  println!("{}", s);
}

• Build the WASM bytecode:

  • cargo build --target wasm32-wasi --release

cargo build --target wasm32-wasi --release

• We will use the wasmedge command to run the program.

$ wasmedge target/wasm32-wasi/release/hello.wasm
Hello WasmEdg
