Enum HelloError 

pub enum HelloError {
    NotHello,
    BadName,
    MissingVersion,
    BadVersion,
    UnsupportedVersion(u32),
    MissingStreamKind,
    UnknownStreamKind(String),
}

Why a line was not a usable HELLO.

Variants

NotHello

Not a handshake at all — treat the connection as a raw stream.

BadName

A handshake with an unusable name.

MissingVersion

A HELLO with no version field at all. Nothing is deployed yet, so this ambiguity is cheapest to close now rather than silently assuming version 1.

BadVersion

A version field that isn’t a bare non-negative integer.

UnsupportedVersion(u32)

A well-formed version this console does not speak.

MissingStreamKind

The old two-field HELLO <version> <name> form: there is no way to tell whether the missing field was meant to be a kind or a name, and guessing is exactly the ambiguity this error avoids.

UnknownStreamKind(String)

A well-formed kind field that isn’t tokens or trace.
