json_str

Docs and samples

Provides an easy way to build json strings in Rust without having to use ungainly strings on stable and nightly channels. Rust has a json-like syntax for defining structures, so it's easy to convert some valid Rust token trees into json. This crate will also minify whitespace and standardise quotes while it's building the String. It's an otherwise very simple sanitiser that doesn't do any escaping within values or support interpolation.

On stable, conversion is provided by a simple macro. On nightly, conversion is provided by a compiler plugin that sanitises the input at compile time instead of runtime. The nightly channel also provides an alternative plugin for creating &str literals instead of Strings, to avoid that allocation.
