Enum RpcError 

pub enum RpcError {
    TooLarge,
    Encode,
    Send(String),
    Timeout,
    Incomplete {
        received: usize,
        total: u16,
    },
    ChannelClosed,
    Busy,
}

Why a call did not complete.

Variants

TooLarge

The request body exceeds aux_rpc::MAX_REQUEST_BODY. The HTTP caller should surface a 413.

Encode

A request field (target, path, content type, ticket) is too long to encode. The HTTP caller should surface a 400.

Send(String)

The aux egress failed to send the request datagram.

Timeout

No response arrived before the bound elapsed.

Incomplete

Some fragments arrived and the rest did not. Distinct from Timeout on purpose: “the drone never answered” and “the radio dropped a fragment” are different faults with different operator actions.

Fields

received: usize

total: u16

ChannelClosed

The consumer torn down between the request and the response, so the pending entry was removed. The caller may retry.

Busy

Too many calls already in flight. Shedding here is honest: the lane cannot deliver them, and queueing would only convert a fast 503 into a slow timeout.

Trait Implementations

impl Clone for RpcError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RpcError

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

Formats the value using the given formatter.

impl Display for RpcError

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

Formats the value using the given formatter.

impl Eq for RpcError

impl Error for RpcError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RpcError

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

Equality operator ==.

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

Inequality operator !=.
