Struct AppErrorPayload 

pub struct AppErrorPayload<'a> {
    pub code: u16,
    pub message: &'a str,
}

Payload carried inside a Response when status == ResponseStatus::AppError.

Encoded as postcard (varint(code), varint(len), len-bytes UTF-8 message). Borrows the message slice from the receive buffer for zero-copy decode on targets that cannot allocate.

Wire layout

Field	Type	Encoding
code	u16	postcard varint (1–3 bytes)
message	&str	postcard varint(len) + UTF-8 bytes

The code namespace is application-defined. Reserve 0 as a catch-all “unspecified application error” when no finer classification is needed.

Fields

code: u16

Application-defined error code.

message: &'a str

Human-readable error message, borrowed from the receive buffer.

Trait Implementations

impl<'a> Clone for AppErrorPayload<'a>

fn clone(&self) -> AppErrorPayload<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for AppErrorPayload<'a>

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

Formats the value using the given formatter.

impl<'de: 'a, 'a> Deserialize<'de> for AppErrorPayload<'a>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> PartialEq for AppErrorPayload<'a>

fn eq(&self, other: &AppErrorPayload<'a>) -> 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<'a> Serialize for AppErrorPayload<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
