Expand description

Errors that can be produced by FIDL clients and servers.

Variants§

TransportError(E)

The underlying transport encountered an error.

Stopped

The underlying transport was stopped gracefully.

PeerClosed

The underlying transport was closed by the peer.

PeerClosedWithEpitaph(i32)

The underlying transport was closed by the peer with an epitaph.

InvalidMessageHeader(DecodeError)

The client or server received a message with an invalid protocol header.

InvalidEpitaphBody(DecodeError)

The client received an epitaph with an invalid body.

UnrequestedResponse

The client received a response for a two-way message which it did not send.

Fields

§txid: u32

The transaction ID which there is no pending response for.

InvalidResponseOrdinal

The client received a response with the wrong ordinal for the two-way message.

Fields

§expected: u64

The expected ordinal of the response

§actual: u64

The actual ordinal of the response
