Interface AsyncResult<V, E>

Transforms the error value if this is an async Err result, using a function that returns another Result.

This method is useful for recovering from failures and flattening chains of async results that operate on errors.

If this is an async Ok result, its success value is preserved unchanged.

Replaces the error value with an Ok result using a raw value.

Equivalent to writing:

result.catchAsync((e) => Promise.resolve(Res.ok(value)))
Copy

If this is an async Ok result, its success value is preserved unchanged.

Returns the underlying Result object.

Transforms the success value if this is an async Ok result, using a function that returns another Result.

This method is useful to flatten chained async results.

If this is an async Err result, its error value is preserved unchanged.

Transforms the success value if this is an async Ok result, using a raw value.

Example:

// getCores(): Promise<Result<number, Error>
// adjustCores(n): Promise<number>
const r = Res.from(getCores()).mapAsync((n) => adjustCores(n));
// r: AsyncResult<number, Error>
Copy

If this is an Err result, its error value is preserved unchanged.

Exhaustively handles both the async Ok and Err result variants.

Example:

const r = await result.match(
  (v) => // Ok branch
  (e) => // Err branch
)
Copy

Invokes the fnv function with the success value if this is an async Ok result, or the fne function if this is an async Err result.

The async result is returned unchanged.

Returns the success value if this is an async Ok result, or throws if this is an async Err result.

Returns the success value if this is an async Ok result, or falls back to the value produced by the given function if this is an async Err result.
