fp-ts-iterable v4.2.6

fp-ts-iterable

fp-ts bindings for Iterable types, allowing for programming lazy and infinite lists.

This could (soon) be used as a drop in replacement for the module fp-ts/ReadonlyArray

Installation

# npm
npm install fp-ts-iterable

# yarn
yarn add fp-ts-iterable

# pnpm
pnpm add fp-ts-iterable

Upcoming

• Structures
  • IterableTask for interop with AsyncIterator
  • NonemptyIterable
  • NonempyIterableTask

Recommendations

Coersion from types that are Iterable

• If coersing from something like a ReadonlyArray, it's recommended to coerce it to an Iterable using FromReadonlyArray.
• There is no performance benefit, but it could alleviate bugs before they happen.

\*Right* functions

• All functions using the word Right in their names require buffering all values so it knows where the end is.
• If the Iterable is large or infinite, it may cause an out of memory error. Ensure infinite iterables end by using a skip combinator that does not contain the word Right.

AsyncIterable (Upcoming)

• AsyncIterable<A> is Iterable<Promise<A>>, but should be coerced to Iterable<Task<A>> via FromAsyncIterable
