This library contains a collection of tools to help interacting with json encoded data.

Features

• Simple Json Lexer
  • Without any intention of being feature complete, it is able to split ascii json data streams into their lexical tokens, keeping track of the character spans that make them up.
  • facilitates writing higher-level parsers and filters
• Key-Value Filter
  • A utility to filter lexical tokens which belong to keys that have values of a given type. This makes it easy to re-assemble json data streams and strip them off their null values, for example.
• TokenReader
  • An adapter to convert a stream of Tokens into a stream of bytes, supprting the Read trait.
  • Use it to convert filtered and/or manipulated token-streams back into byte-streams.
  • Configure the output style, to achieve effects like pretty-printing or strip the output of all whitespace.

Usage

Add this to your Cargo.toml toml [dependencies] json-tools = "*"

Add this to your lib ... ```Rust extern crate json_tools;

use json_tools::Lexer;

for token in Lexer::new(r#"{ "face": "😂" }"#.bytes()) { println!("{:?}", token); } ```

Motivation

This library may possibly never grow bigger than the two features originally mentioned, as it was created as a workaround to missing features in serde.
