Struct JsonStringDecoder 

pub struct JsonStringDecoder;

Stateless default decoder for payloads stored as String.

The unit struct is zero-sized and may be copied freely while configuring decoder registries. Every registry entry still binds it to exactly one key and to the concrete String output type.

Trait Implementations

impl Clone for JsonStringDecoder

fn clone(&self) -> JsonStringDecoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JsonStringDecoder

impl Debug for JsonStringDecoder

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

Formats the value using the given formatter.

impl Default for JsonStringDecoder

fn default() -> JsonStringDecoder

Returns the “default value” for a type.

impl JsonPayloadDecoder<String> for JsonStringDecoder

fn decode_json_payload(&self, raw_json: &str) -> Result<String, Self::Error>

Deserializes one complete JSON string into an owned String.

The returned value owns its UTF-8 buffer. On failure, the original serde_json::Error is returned so the decoder registry can retain it as the source of a stream-, index-, and key-aware storage error.

type Error = Error

Decoder-specific failure retained by StorageError::DecodeField.
