json-lines is a `#![no_std]` + serde compatible message library implementing the
JSON Lines format.

# High-level overview

The crate provides a Rust-language implementation of JSON Lines (JSONL),
also known as Newline-Delimited JSON (NDJSON).

The wikipedia page [JSON
Streaming](https://en.wikipedia.org/wiki/JSON_streaming) and
[jsonlines.org](https://jsonlines.org) are good resources describing the
format.

This crate endeavors to have a similar API to the
[postcard](https://crates.io/crates/postcard) crate. This way, Rust code can
easily switch between JSONL and postcard formats depending on requirements.
JSONL is "self-describing" but less efficient, whereas postcard is very compact
but requires an out-of-band knowledge of message structure.

The crate contains a `#![no_std]` implementation for use in, e.g. embedded
contexts. The `std` feature is enabled by default and provides things such as
the [Error] enum implements the [std::error::Error] Trait.

The `codec` feature enables compilation of [crate::codec::JsonLinesCodec], which
provides an implementation of [tokio_util::codec::Decoder] and
[tokio_util::codec::Encoder].
