Struct JsonRpcEnvelope 

pub struct JsonRpcEnvelope {
    pub id: Option<JsonRpcId>,
    pub method: Option<String>,
    pub params: Option<Box<RawValue>>,
    pub result: Option<Box<RawValue>>,
    pub error: Option<JsonRpcError>,
}

Shallow parse of a single JSON-RPC 2.0 message.

Fields

id: Option<JsonRpcId>

method: Option<String>

params: Option<Box<RawValue>>

result: Option<Box<RawValue>>

error: Option<JsonRpcError>

Implementations

impl JsonRpcEnvelope

pub fn parse(bytes: &[u8]) -> Result<Self, ParseError>

Parse a single JSON-RPC 2.0 message. Rejects batches.

pub fn params_as<T: DeserializeOwned>(&self) -> Option<T>

Deserialize params into T. Returns None if params is absent or does not match T’s shape.

pub fn result_as<T: DeserializeOwned>(&self) -> Option<T>

Deserialize result into T. Returns None if result is absent or does not match T’s shape.

pub fn to_bytes(&self) -> Vec<u8>

Reassemble the envelope into JSON-RPC 2.0 bytes.

Used when forwarding upstream (request body) and when sealing a buffered response. The inner RawValue fields are re-inlined verbatim — no re-parsing. Parse failures on the cached bytes would have been caught by JsonRpcEnvelope::parse, so we default to Null rather than panic.

Trait Implementations

impl Clone for JsonRpcEnvelope

fn clone(&self) -> JsonRpcEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsonRpcEnvelope

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

Formats the value using the given formatter.
