The enumerated type for the tlsEarlyData 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.

Disabled

TLS 1.3 Early Data is not advertised, and any (invalid) attempts to send Early Data will be rejected by closing the connection.

Permissive

This enables TLS 1.3 0-RTT, and only allows Early Data to be included on requests with safe HTTP methods (GET, HEAD, OPTIONS, TRACE). This mode does not enforce any other limitations for requests with Early Data. The application owner should validate that Early Data is acceptable for a given request path.

Strict

This enables TLS 1.3 0-RTT, and only allows Early Data to be included on requests with safe HTTP methods (GET, HEAD, OPTIONS, TRACE) without query parameters. Requests that send Early Data with non-idempotent HTTP methods or with query parameters will be rejected with a HTTP 425.

Unrestricted

This enables TLS 1.3 Early Data for requests with any HTTP method including non-idempotent methods list POST. This mode does not enforce any other limitations. This may be valuable for gRPC use cases. However, we do not recommend this method unless you have evaluated your security stance and mitigated the risk of replay attacks using other mechanisms.

UnknownValue(UnknownValue)

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

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

Implementations

impl TlsEarlyData

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 TlsEarlyData

fn clone(&self) -> TlsEarlyData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TlsEarlyData

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

Formats the value using the given formatter.

impl Default for TlsEarlyData

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TlsEarlyData

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TlsEarlyData

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

Formats the value using the given formatter.

impl From<&str> for TlsEarlyData

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for TlsEarlyData

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for TlsEarlyData

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

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

where S: Serializer,

Serialize this value into the given Serde serializer.
