Enum CallHomeAnnounceError 

pub enum CallHomeAnnounceError {
    TimedOut,
    Frame(FrameError),
    BuildStamp {
        announced: String,
    },
    InvalidNodeId,
}

Why a call-home preface could not be read.

Variants

TimedOut

The socket said nothing, or not enough, before the deadline.

Frame(FrameError)

The bytes were not a well-formed preface.

BuildStamp

A preface arrived, from a peer built from a different tree than this binary. Reported separately from Frame because it is the one failure here that is a deployment mistake rather than a hostile or broken peer, and it should read as one in a log.

Fields

announced: String

InvalidNodeId

The name is not a syntactically valid node id. Checked here rather than left to the lookup so a malformed name is refused at the door with a reason, instead of becoming an indistinguishable “no such node” a moment later.

Trait Implementations
