library.getFunctions([definitions])
当提供 definitions 时,解析每个命名符号并返回一个包含可调用封装器的对象。
🌐 When definitions is provided, resolves each named symbol and returns an
object containing callable wrappers.
当省略 definitions 时,返回库中所有已解析函数的封装器。
🌐 When definitions is omitted, returns wrappers for all functions that have
already been resolved on the library.
