Struct JsonCodec 

pub struct JsonCodec;

A StateCodec that uses serde_json for all keys and values.

Trait Implementations

impl Clone for JsonCodec

fn clone(&self) -> JsonCodec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsonCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JsonCodec

fn default() -> JsonCodec

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JsonCodec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JsonCodec

fn eq(&self, other: &JsonCodec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for JsonCodec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StateCodec for JsonCodec

type KeyCodec = JsonCodec

The codec used to serialize keys. See StateKeyCodec.

type ValueCodec = JsonCodec

The codec used to serialize and deserialize values. See StateValueCodec.

fn key_codec(&self) -> &Self::KeyCodec

Returns a reference to the type’s key codec.

fn value_codec(&self) -> &Self::ValueCodec

Returns a reference to the type’s value codec.

impl<K> StateKeyCodec<K> for JsonCodec

where K: Serialize,

fn encode_key(&self, key: &K) -> Vec<u8>

Serializes a key into a bytes vector.

impl<V> StateValueCodec<V> for JsonCodec

where V: Serialize + for<'a> Deserialize<'a>,

type Error = Error

Error type that can arise during deserialization.

fn encode_value(&self, value: &V) -> Vec<u8>

Serializes a value into a bytes vector.

fn try_decode_value(&self, bytes: &[u8]) -> Result<V, Self::Error>

Tries to deserialize a value from a bytes slice, and returns a Result with either the deserialized value or an error.

fn decode_value_unwrap(&self, bytes: &[u8]) -> V

Deserializes a value from a bytes slice.
