applyCloudflareWorkersFunctions function

Future<bool> applyCloudflareWorkersFunctions({ required String alias, required String package, required Map<String, String> functions, })

Apply Cloudflare Workers functions to cloudflare/src/index.ts.

Ensures the import of package with alias, and inserts each entry of functions (a map of function name to the code to insert) into m.deploy([...]) if it does not already exist. Existing calls are replaced.

cloudflare/src/index.tsにCloudflare WorkersのFunctionを適用します。

alias付きのpackageのimportを保証し、functions（関数名から挿入コードへのマップ)の 各エントリーが存在しない場合はm.deploy([...])に挿入します。既存の呼び出しは置き換えられます。
