Enum ProxyV2Error 

pub enum ProxyV2Error {
    BadSignature,
    BadVersion(u8),
    BadCommand(u8),
    UnsupportedFamilyProtocol(u8),
    DeclaredLenTooLarge {
        declared: usize,
    },
    AddressBlockTooShort {
        declared: usize,
        need: usize,
    },
}

Why a byte sequence is not a valid v2 header. Every variant is a connection-fatal fault code (fail-closed, ADR 000057) — there is no “tolerate and pass through”.

Variants

BadSignature

BadVersion(u8)

BadCommand(u8)

UnsupportedFamilyProtocol(u8)

PROXY with anything but TCP over IPv4/IPv6 (AF_UNSPEC / AF_UNIX / DGRAM / reserved): rejected per ADR 000057 — the listener is a TCP fast path; an unspecified peer identity must not silently degrade to the LB’s address.

impl Eq for ProxyV2Error

impl Error for ProxyV2Error

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.
