tinyjson is a library to parse/generate JSON format document.
Goals of this library are
Vec
or HashMap
as its internal representation and exposes it to users. Users can operate JSON values via the standard APIs. And it keeps this crate as small as possible.Vec
, String
, HashMap
by yourself. It is good for readers of your source code to show where memory allocations happen. And you can have control of how memory is allocated (e.g. allocating memory in advance with with_capacity
method).Rust stable toolchain.
Add this crate to dependencies
section of your Cargo.toml
[dependencies] tinyjson = "2"
