If you're new to this library, you may need a few pointers of where to look for features:
Preludeis astatic partial class, this type is loaded with functions for constructing the key data types, as well as many of the things you'd expect in a functional programming language's prelude. Note, thePreludetype extends into many other parts of the source-tree. It's the same type, but spread all over the code-base. And so, you may seePreludein other areas of the documentation: it's the same type.Because it's so fundamental, you'll want to add this to the top of every code file:
using static LanguageExt.Prelude;This makes all of the functions in the
Preludeavailable as though they were local.Monadscontains the common monads likeOption<A>andEither<L, R>, as well as state-managing monads likeReader,Writer, andState.Immutable Collectionscontains the high-performance functional collection types this library is famous for.Effectsis where the pure IO functionality of language-ext resides. It is also where you'll find thePipescompositional streaming functionality. To understand more about how to deal with side-effects, check the wiki.Concurrencyis where you'll find lots of help in atomically managing shared data without locks.
