Available on crate features backend-services or region-backend-services only.

The enumerated type for the protocol field.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

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.

Grpc

gRPC (available for Traffic Director).

H2C

HTTP2 over cleartext

Http

Http2

HTTP/2 with SSL.

Https

Ssl

TCP proxying with SSL.

Tcp

TCP proxying or TCP pass-through.

Udp

UDP.

Unspecified

If a Backend Service has UNSPECIFIED as its protocol, it can be used with any L3/L4 Forwarding Rules.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using Protocol::value or Protocol::name.

Implementations

impl Protocol

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.

Trait Implementations

impl Clone for Protocol

fn clone(&self) -> Protocol

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Protocol

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

Formats the value using the given formatter.

impl Default for Protocol

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Protocol

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Protocol

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

Formats the value using the given formatter.

impl From<&str> for Protocol

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for Protocol

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for Protocol

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Protocol

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

where S: Serializer,

Serialize this value into the given Serde serializer.
