Struct Json 

pub struct Json<T>(pub T);

Json is a type wrapper to implement Footer for all types that implement serde_core::Serialize and serde_core::Deserialize

When using a JSON footer, you should be aware of the risks of parsing user provided JSON. https://github.com/paseto-standard/paseto-spec/blob/master/docs/02-Implementation-Guide/01-Payload-Processing.md#storing-json-in-the-footer.

Currently, this uses serde_json internally, which by default offers a stack-overflow protection limit on parsing JSON. You should also parse into a known struct layout, and avoid arbitrary key-value mappings.

If you need stricter checks, you can make your own Footer encodings that give access to the bytes before the footer is decoded.

Trait Implementations

impl<T: Default> Default for Json<T>

fn default() -> Json<T>

Returns the “default value” for a type.

impl<T: Serialize + DeserializeOwned> Footer for Json<T>

fn encode( &self, writer: impl WriteBytes, ) -> Result<(), Box<dyn Error + Send + Sync>>

Encode the footer to bytes

fn decode(footer: &[u8]) -> Result<Self, Box<dyn Error + Send + Sync>>

Decode the footer from bytes

impl<M: Serialize + DeserializeOwned> Payload for Json<M>

const SUFFIX: &'static str = ""

JSON is the standard payload and requires no version suffix

fn encode( self, writer: impl WriteBytes, ) -> Result<(), Box<dyn Error + Send + Sync>>

Encode the message

fn decode(payload: &[u8]) -> Result<Self, Box<dyn Error + Send + Sync>>

Decode the message
