fromPromise

fromPromise<A>(p): Deferred<A>

Defined in: Core/Deferred.ts:42

Wraps a Promise into a Deferred, structurally excluding rejection handlers, .catch(), .finally(), and chainable .then().

Precondition: p must never reject. If p rejects, the returned Deferred will never resolve — await-ing it will hang indefinitely. Use TaskResult.tryCatch to handle operations that may fail before converting to a Deferred.

Type Parameters

A

A

Parameters

p

Promise<A>

Returns

Deferred<A>

Example

const d = Deferred.fromPromise(Promise.resolve("hello"));
const value = await d; // "hello"
