# 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 as `pub extern "C" $name`.
|
||||
- Asserts that the function symbol is present in
|
||||
[`symbol_exports.json`](./symbol_exports.json).
|
||||
- Maps `deno_napi::Result` to raw `napi_result`.
|
||||
|
||||
```rust
|
||||
use deno_napi::{napi_value, Env, Error, 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`](../build.rs).
|
||||
|
||||
On Windows, you need to generate the `.def` file by running
|
||||
[`tools/napi/generate_symbols_lists.js`](../../tools/napi/generate_symbols_lists.js).
