Std.Json.foldLines

fn

This is a callable function.

What it does

Combine every value of a JSON Lines file, one value to a line, holding one

chunk of the file at a time.

A line holding only whitespace is skipped, so a file that ends with a blank

line is still read. Values before a malformed line have already reached

step; after it, the rest of the file is read without further work.

Read the signature

• Read arrows from left to right: inputs come first, and the final type is returned.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Result makes success and recoverable failure part of the function's type.
