//! Symbols to be exported are now defined in this JSON file.
|
|
//! The `#[napi_sym]` macro checks for missing entries and panics.
|
|
//!
|
|
//! `./tools/napi/generate_symbols_list.js` is used to generate the LINK `cli/exports.def` on Windows,
|
|
//! which is also checked into git.
|
|
//!
|
|
//! To add a new napi function:
|
|
//! 1. Place `#[napi_sym]` on top of your implementation.
|
|
//! 2. Add the function's identifier to this JSON list.
|
|
//! 3. Finally, run `tools/napi/generate_symbols_list.js` to update `cli/napi/generated_symbol_exports_list_*.def`.
