本文整理匯總了TypeScript中async-done.default函數的典型用法代碼示例。如果您正苦於以下問題：TypeScript default函數的具體用法？TypeScript default怎麽用？TypeScript default使用的例子？那麽, 這裏精選的函數代碼示例或許可以為您提供幫助。
在下文中一共展示了default函數的4個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的TypeScript代碼示例。
示例1: success
function success(): Observable<undefined> {
return Observable.empty();
}
function successValue(): Observable<number> {
return Observable.of(42);
}
function failure(): Observable<number> {
return Observable.throw(new Error("Observable error"));
}
// `success` callback
asyncDone(success, function (err: Error | null): void {
console.log("Done");
});
// The following code fails to compile as expected (`undefined` is not assignable to `number`):
// asyncDone(success, function (err: Error | null, result: number): void {
// console.log("Done");
// });
// `successValue` and stricter callback
asyncDone(successValue, function (err: Error | null, result?: number): void {
console.log("Done");
});
// `successValue` and unsound callback
asyncDone(successValue, function (err: Error | null, result: number): void {
console.log("Done");示例2: streamSuccess
import asyncDone from "async-done";
import { Readable, Stream } from "stream";
function streamSuccess(): Stream {
return new Stream();
}
function streamFail(): Stream {
return new Stream();
}
asyncDone(streamSuccess, function (err: Error | null): void {
console.log("Done");
});
asyncDone(streamFail, function (err: Error | null): void {
console.log("Done");
});
示例3: success
import asyncDone from "async-done";
import cp from "child_process";
function success(): cp.ChildProcess {
return cp.exec("echo hello world");
}
function failure(): cp.ChildProcess {
return cp.exec("foo-bar-baz hello world");
}
asyncDone(success, function (err: Error | null): void {
console.log("Done");
});
asyncDone(failure, function (err: Error | null): void {
console.log("Done");
});
示例4: setTimeout
import asyncDone, {AsyncTask, VoidCallback} from "async-done";
// Do not error if the return value is not `void`.
const fn: AsyncTask = (cb: VoidCallback): NodeJS.Timer => setTimeout(cb, 1000);
asyncDone(fn, () => {});
