If you're new to this library, you may need a few pointers of where to look for features:
Prelude
is 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, thePrelude
type 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 seePrelude
in 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 (or in your global usings):
using static LanguageExt.Prelude;
This makes all functions in the
Prelude
available as though they were local.Traits
are the powerhouse of this library and allow for true higher-kinded abstract behviours to be leveraged throughout. The topic of traits is huge, so if you're looking for an introduction, take a look at Paul Louth's Higher Kinds series on his blog.Monads
contains the common monads likeOption<A>
andEither<L, R>
, as well as state-managing monads likeReader
,Writer
, andState
. It also is home to many monad-transformers (types with aT
suffix, likeOptionT
). Transformers allow 'stacking' of monadic effects into 'super monads'.Immutable Collections
contains the high-performance functional collection types this library is famous for.Effects
is where the pure IO functionality of language-ext resides. It is also where you'll find theStreamT
for 'effectful' streaming. To understand more about how to deal with side-effects, check the wiki.Concurrency
is where you'll find lots of help in atomically managing shared data without locks.
