Enum Type 

pub enum Type {
    ALPN,
    Authority,
    CRC32C,
    NoOp,
    UniqueId,
    SSL,
    SSLVersion,
    SSLCommonName,

    SSLSignatureAlgorithm,

    NetworkNamespace,
    Unknown(u8),
}

Available on crate feature haproxy only.

Supported types for TypeLengthValue payloads.

Unknown TLV kinds are preserved as Type::Unknown(u8) so that callers can still inspect or forward vendor-specific TLVs (e.g. AWS VPC endpoint 0xEA, Azure PRIVATELINK 0xEE, GCP PSC TLVs) without losing fidelity.

Variants

ALPN

The ALPN of the connection.

Authority

The authority of the connection (e.g. SNI host name).

CRC32C

The CRC32C checksum of the header.

NoOp

NoOp — padding / alignment.

UniqueId

The unique connection ID assigned by the upstream proxy.

SSL

SSL information block (carries sub-TLVs).

SSLVersion

The SSL version.

SSLCommonName

The SSL common name.

SSLCipher

The SSL cipher.

SSLSignatureAlgorithm

The SSL signature algorithm.

SSLKeyAlgorithm

The SSL key algorithm.

NetworkNamespace

The Linux network namespace name.

Unknown(u8)

Retains an unrecognized numeric value.

Implementations

impl Type

pub fn variant_name(&self) -> Cow<'static, str>

Return this value’s variant name, or its decimal number when the value is unknown.

Known values borrow their 'static mnemonic, and unknown values render their numeric value. Unlike Display and Debug the result is a bare, stable label, suitable for log fields, metrics, and telemetry.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Type

impl Debug for Type

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Type

fn deserialize<D>( deserializer: D, ) -> Result<Type, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Type

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

Formats the value using the given formatter.

impl Eq for Type

impl From<Type> for u8

fn from(value: Type) -> u8

Converts to this type from the input type.

impl From<u8> for Type

fn from(x: u8) -> Type

Converts to this type from the input type.

impl Hash for Type

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for Type

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

Formats the value using the given formatter.

impl Ord for Type

fn cmp(&self, other: &Type) -> Ordering

Compare by numeric value, then distinguish colliding variants.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Type

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Type

fn partial_cmp(&self, other: &Type) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Type

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Type

impl UpperHex for Type

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

Formats the value using the given formatter.

impl WriteToHeader for Type

fn write_to(&self, writer: &mut Writer) -> Result<usize, Error>

Write this instance to the given Writer. The Writer returns an IO error when an individual byte slice is longer than u16::MAX. However, the total length of the buffer may exceed u16::MAX.

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Writes this instance to a temporary buffer and returns the buffer.
