The Result.Base type to unwrap.
The Result to unwrap.
The success value if Result.Ok, otherwise undefined.
const okResult = Result.ok(42);
const errResult = Result.err('oops');
// Result.unwrapOk returns the value for Ok results
assert(Result.unwrapOk(okResult) === 42);
// Result.unwrapOk returns undefined for Err results
// eslint-disable-next-line @typescript-eslint/no-confusing-void-expression
assert(Result.unwrapOk(errResult) === undefined);
Unwraps a Result, returning the success value or undefined if it's an
error.
This function provides a safe way to extract success values from Results without throwing exceptions. It has overloaded behavior based on the type:
Result.Ok<T>: Always returns T (guaranteed by type system)Result<T, E>: Returns T | undefinedThe Result to unwrap.
