The AsyncEither datastructure represents an asynchronous operation that can
fail. At its heart it is implemented as () => Promise<Either<B, A>>
. This
thunk makes it a performant but lazy operation at the expense of stack
safety.
alt | Provide an alternative for a failed computation. Useful for implementing defaults. |
apply | Apply an argument to a function under the Right side. |
applySequential | Sequentially apply arguments |
fail | Construct an AsyncEither<B, A> from a value B. |
flatmap | Chain AsyncEither based computations together in a pipeline |
flatmapFirst | |
fromAsync | Lift an always succeeding async computation (Async) into a AsyncEither. |
fromEither | Lifts an Either<B,A> into a AsyncEither<B, A>. |
getCombinableAsyncEither | |
getInitializableAsyncEither | |
left | Constructs a AsyncEither from a value and wraps it in an inner Left traditionally signaling a failure. |
map | Map a function over the Right side of a AsyncEither |
mapSecond | Map a function over the Left side of a AsyncEither |
match | Fold away the inner Either from the |
recover | Chain AsyncEither based failures, Left sides, useful for recovering from error conditions. |
right | Constructs a AsyncEither from a value and wraps it in an inner Right traditionally signaling a successful computation. |
tryCatch | Wraps a Async of A in a try-catch block which upon failure returns B instead. Upon success returns a Right and Left for a failure. |
wrap | Construct an AsyncEither<B, A> from a value A. |
KindAsyncEither | Specifies AsyncEither as a Higher Kinded Type, with covariant parameter A corresponding to the 0th index of any substitutions and covariant parameter B corresponding to the 1st index of any substitutions. |
AsyncEither | The AsyncEither type can best be thought of as an asynchronous function that
returns an |
