Enum google_api_proto::google::cloud::compute::v1::backend_service_connection_tracking_policy::ConnectionPersistenceOnUnhealthyBackends

#[repr(i32)]
pub enum ConnectionPersistenceOnUnhealthyBackends {
    UndefinedConnectionPersistenceOnUnhealthyBackends = 0,
    AlwaysPersist = 38_400_900,
    DefaultForProtocol = 145_265_356,
    NeverPersist = 138_646_241,
}

Specifies connection persistence when backends are unhealthy. The default value is DEFAULT_FOR_PROTOCOL. If set to DEFAULT_FOR_PROTOCOL, the existing connections persist on unhealthy backends only for connection-oriented protocols (TCP and SCTP) and only if the Tracking Mode is PER_CONNECTION (default tracking mode) or the Session Affinity is configured for 5-tuple. They do not persist for UDP. If set to NEVER_PERSIST, after a backend becomes unhealthy, the existing connections on the unhealthy backend are never persisted on the unhealthy backend. They are always diverted to newly selected healthy backends (unless all backends are unhealthy). If set to ALWAYS_PERSIST, existing connections always persist on unhealthy backends regardless of protocol and session affinity. It is generally not recommended to use this mode overriding the default. For more details, see Connection Persistence for Network Load Balancing and Connection Persistence for Internal TCP/UDP Load Balancing.

Variants

UndefinedConnectionPersistenceOnUnhealthyBackends = 0

Implementations

impl ConnectionPersistenceOnUnhealthyBackends

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of ConnectionPersistenceOnUnhealthyBackends.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl ConnectionPersistenceOnUnhealthyBackends

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 ConnectionPersistenceOnUnhealthyBackends

fn clone(&self) -> ConnectionPersistenceOnUnhealthyBackends

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionPersistenceOnUnhealthyBackends

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

Formats the value using the given formatter.

impl Default for ConnectionPersistenceOnUnhealthyBackends

fn default() -> ConnectionPersistenceOnUnhealthyBackends

Returns the “default value” for a type.

impl From<ConnectionPersistenceOnUnhealthyBackends> for i32

fn from(value: ConnectionPersistenceOnUnhealthyBackends) -> i32

Converts to this type from the input type.

impl Hash for ConnectionPersistenceOnUnhealthyBackends

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 ConnectionPersistenceOnUnhealthyBackends

fn cmp(&self, other: &ConnectionPersistenceOnUnhealthyBackends) -> 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 ConnectionPersistenceOnUnhealthyBackends

fn eq(&self, other: &ConnectionPersistenceOnUnhealthyBackends) -> 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 ConnectionPersistenceOnUnhealthyBackends

fn partial_cmp( &self, other: &ConnectionPersistenceOnUnhealthyBackends, ) -> 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 ConnectionPersistenceOnUnhealthyBackends

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

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

Performs the conversion.
