result library

Classes

Err<S, F extends Object>

Error Result.

Ok<S, F extends Object>

Ok Result.

Result<S, F extends Object>

Result is used for propagating errors and represents the sum type of Ok and Err.

Functions

guard<S>(S func()) → Result<S, Object>

Executes the function in a protected context. func is called inside a try catch block. If the result does not catch, then return value func returned inside an Ok. If func throws, then the thrown value is returned inside an Err.

guardAsync<S>(Future<S> func()) → FutureResult<S, Object>

Async version of guard

guardAsyncResult<S>(Future<Result<S, Object>> func()) → FutureResult<S, Object>

Async version of guardResult

guardResult<S>(Result<S, Object> func()) → Result<S, Object>

Result unwrapping version of guard. Where func returns an Result, but can still throw.

Typedefs

FutureResult<S, F extends Object> = Future<Result<S, F>>

FutureResult represents an asynchronous Result. And as such, inherits all of Results methods.
