napi_sym
A proc_macro for Deno's Node-API implementation. It does the following things:
- Marks the symbol as
#[no_mangle]
and rewrites it aspub extern "C" $name
. - Asserts that the function symbol is present in
symbol_exports.json
. - Maps
deno_napi::Result
to rawnapi_result
.
use deno_napi::napi_value;
use deno_napi::Env;
use deno_napi::Error;
use deno_napi::Result;
#[napi_sym::napi_sym]
fn napi_get_boolean(
env: *mut Env,
value: bool,
result: *mut napi_value,
) -> Result {
let _env: &mut Env = env.as_mut().ok_or(Error::InvalidArg)?;
// *result = ...
Ok(())
}
symbol_exports.json
A file containing the symbols that need to be put into the executable's dynamic symbol table at link-time.
This is done using /DEF:
on Windows, -exported_symbol,_
on macOS and
--export-dynamic-symbol=
on Linux. See cli/build.rs
.
On Windows, you need to generate the .def
file by running
tools/napi/generate_symbols_lists.js
.
