Function wasmer_c_api::wasm_c_api::engine::wasm_config_set_compiler

#[no_mangle]
pub extern "C" fn wasm_config_set_compiler(
    config: &mut wasm_config_t,
    compiler: wasmer_compiler_t,
)

Updates the configuration to specify a particular compiler to use.

This is a Wasmer-specific function.

Example

int main() {
    // Create the configuration.
    wasm_config_t* config = wasm_config_new();

    // Use the Cranelift compiler, if available.
    if (wasmer_is_compiler_available(CRANELIFT)) {
        wasm_config_set_compiler(config, CRANELIFT);
    }
    // Or maybe LLVM?
    else if (wasmer_is_compiler_available(LLVM)) {
        wasm_config_set_compiler(config, LLVM);
    }
    // Or maybe Singlepass?
    else if (wasmer_is_compiler_available(SINGLEPASS)) {
        wasm_config_set_compiler(config, SINGLEPASS);
    }
    // OK, let's run with no particular compiler.

    // Create the engine.
    wasm_engine_t* engine = wasm_engine_new_with_config(config);

    // Check we have an engine!
    assert(engine);

    // Free everything.
    wasm_engine_delete(engine);

    return 0;
