Documentation crates.io

This is full-featured modern JSON implementation according to ECMA-404 standard.

This crate allows deserialization of JSON Iterator<u8> stream into primitive types (bool, i32, etc.), Strings and any other types that implement special trait called TryFromJson, which can be implemented automatically through #[derive(TryFromJson)] for your structs and enums.

And serialization back to JSON through DebugToJson trait, that acts like Debug, allowing to print your objects with println!() and such. Or through WriteToJson trait that allows to write to a io::Write stream.

This crate allows to read whitespece-separated JSON values from stream in sequence. It also allows to pipe blob strings to a writer.
