unwrap

function Result.unwrap(result: Result<T, E>): T

Unwraps the Ok value from the result. If the result is an Err, throws a ResultError with a default message.

Example

data-first

Result.unwrap(ok(5));
// 5

Result.unwrap(err("fail"));
// throws ResultError("Called Err.unwrap()")

data-last

pipe(ok(5), Result.unwrap());
// 5
