Why a PROXY header was refused.

assert_eq!(net_io::ProxyError::V1TooLong.to_string(), "v1 header longer than 107 bytes");

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OutputTooSmall

encode: the output buffer cannot hold the header.

Fields

need: usize

Bytes needed.

NotProxy

The first bytes match no allowed signature.

V1TooLong

A v1 line longer than 107 bytes.

V1Syntax

A v1 line that does not follow the grammar.

Fields

at: u8

Byte offset of the problem.

V1BadAddress

A v1 address that does not parse.

V1BadPort

A v1 port that does not parse.

V2BadVersion

A v2 version nibble other than 2.

V2BadCommand

A v2 command other than LOCAL or PROXY.

V2BadFamily

A v2 family and transport byte not in the specification.

V2LengthTooLarge

A v2 length above the configured maximum.

Fields

declared: u16

The declared length.

max: u16

The maximum.

V2AddressTooShort

A v2 address block shorter than its family needs.

V2TlvOverrun

A v2 TLV that runs past the declared length.

V2CrcMismatch

A v2 CRC32C TLV that does not match.

V2UniqueIdTooLong

A v2 unique id longer than 128 bytes.

V2SslMalformed

A v2 SSL TLV that does not parse.

FamilyMismatch

Addresses of a different family than the header declares.

Trait Implementations

impl Clone for ProxyError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProxyError

impl Debug for ProxyError

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

Formats the value using the given formatter.

impl Display for ProxyError

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

Formats the value using the given formatter.

impl Eq for ProxyError

impl Error for ProxyError

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 ProxyError

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

Equality operator ==.

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

Inequality operator !=.
