}

Type of session affinity to use. The default is NONE. Only NONE and HEADER_FIELD are supported when the backend service is referenced by a URL map that is bound to target gRPC proxy that has validateForProxyless field set to true. For more details, see: Session Affinity.

Variants

UndefinedSessionAffinity = 0

A value indicating that the enum field is not set.

ClientIp = 345_665_051

2-tuple hash on packet’s source and destination IP addresses. Connections from the same source IP address to the same destination IP address will be served by the same backend VM while that VM remains healthy.

ClientIpNoDestination = 106_122_516

1-tuple hash only on packet’s source IP address. Connections from the same source IP address will be served by the same backend VM while that VM remains healthy. This option can only be used for Internal TCP/UDP Load Balancing.

ClientIpPortProto = 221_722_926

5-tuple hash on packet’s source and destination IP addresses, IP protocol, and source and destination ports. Connections for the same IP protocol from the same source IP address and port to the same destination IP address and port will be served by the same backend VM while that VM remains healthy. This option cannot be used for HTTP(S) load balancing.

ClientIpProto = 25_322_148

3-tuple hash on packet’s source and destination IP addresses, and IP protocol. Connections for the same IP protocol from the same source IP address to the same destination IP address will be served by the same backend VM while that VM remains healthy. This option cannot be used for HTTP(S) load balancing.

GeneratedCookie = 370_321_204

Hash based on a cookie generated by the L7 loadbalancer. Only valid for HTTP(S) load balancing.

HeaderField = 200_737_960

The hash is based on a user specified header field.

HttpCookie = 494_981_627

The hash is based on a user provided cookie.

None = 2_402_104

No session affinity. Connections from the same client IP may go to any instance in the pool.

Implementations

impl SessionAffinity

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of SessionAffinity.

pub fn from_i32(value: i32) -> Option<SessionAffinity>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a SessionAffinity, or None if value is not a valid variant.

impl SessionAffinity

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for SessionAffinity

fn clone(&self) -> SessionAffinity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SessionAffinity

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

Formats the value using the given formatter.

impl Default for SessionAffinity

fn default() -> SessionAffinity

Returns the “default value” for a type.

impl From<SessionAffinity> for i32

fn from(value: SessionAffinity) -> i32

Converts to this type from the input type.

impl Hash for SessionAffinity

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

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 Ord for SessionAffinity

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

This method returns an Ordering between self and other.

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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SessionAffinity

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SessionAffinity

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<i32> for SessionAffinity

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<SessionAffinity, UnknownEnumValue>

Performs the conversion.

impl Copy for SessionAffinity

impl Eq for SessionAffinity

impl StructuralPartialEq for SessionAffinity
