explicit_outcome library

A library for the explicit_outcome package.

This library provides utilities for working with explicit outcomes, such as results and options, in a way that promotes explicit and predictable development.

Classes

AsyncOpt<T extends Object>

Lazy asynchronous Opt composition.

AsyncRes<T extends Object, E extends Object>

Lazy asynchronous Res composition.

Err<T extends Object, E extends Object>

A Result representing a failed operation.

Nil<T extends Object>

An Option representing absence of a value.

Ok<T extends Object, E extends Object>

A Result representing a successful operation.

Option<T extends Object>

A generic Option type that represents either a Val value or a Nil (absence of value).

Result<T extends Object, E extends Object>

A generic Result type that represents either an Ok success or an Err error.

Val<T extends Object>

An Option representing a present, non-null value.

Extensions

AsyncOptConveniences on AsyncOpt<T>

Convenience methods for consuming lazy asynchronous Opt values.

Typedefs
