👎Deprecated since 0.30.0:

The opentelemetry-stackdriver crate is deprecated and will be removed from opentelemetry-rust-contrib. Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

An indicator of the behavior of a given field (for example, that a field is required in requests, or given as output but ignored as input). This does not change the behavior in protocol buffers itself; it only denotes the behavior and may affect how API tooling handles the field.

Note: This enum may receive new values in the future.

Unspecified = 0

See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Conventional default for enums. Do not use this.

Optional = 1

Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Specifically denotes a field as optional. While all fields in protocol buffers are optional, this may be specified for emphasis if appropriate.

Required = 2

👎Deprecated since 0.30.0:

Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Denotes a field as required. This indicates that the field must be provided as part of the request, and failure to do so will cause an error (usually INVALID_ARGUMENT).

OutputOnly = 3

👎Deprecated since 0.30.0:

The opentelemetry-stackdriver crate is deprecated and will be removed from opentelemetry-rust-contrib. Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Denotes a field as output only. This indicates that the field is provided in responses, but including the field in a request does nothing (the server must ignore it and must not throw an error as a result of the field’s presence).

InputOnly = 4

👎Deprecated since 0.30.0:

The opentelemetry-stackdriver crate is deprecated and will be removed from opentelemetry-rust-contrib. Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Denotes a field as input only. This indicates that the field is provided in requests, and the corresponding field is not included in output.

Immutable = 5

Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Denotes a field as immutable. This indicates that the field may be set once in a request to create a resource, but may not be changed thereafter.

UnorderedList = 6

👎Deprecated since 0.30.0:

Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Denotes that a (repeated) field is an unordered list. This indicates that the service may provide the elements of the list in any arbitrary order, rather than the order the user originally provided. Additionally, the list’s order may or may not be stable.

NonEmptyDefault = 7

👎Deprecated since 0.30.0:

Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Denotes that this field returns a non-empty default value if not set. This indicates that if the user provides the empty value in a request, a non-empty value will be returned. The user will not be aware of what non-empty value to expect.

Identifier = 8

👎Deprecated since 0.30.0:

The opentelemetry-stackdriver crate is deprecated and will be removed from opentelemetry-rust-contrib. Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Denotes that the field in a resource (a message annotated with google.api.resource) is used in the resource name to uniquely identify the resource. For AIP-compliant APIs, this should only be applied to the name field on the resource.

This behavior should not be applied to references to other resources within the message.

The identifier field of resources often have different field behavior depending on the request it is embedded in (e.g. for Create methods name is optional and unused, while for Update methods it is required). Instead of method-specific annotations, only IDENTIFIER is required.

Implementations

impl FieldBehavior

pub fn is_valid(value: i32) -> bool

👎Deprecated since 0.30.0:

The opentelemetry-stackdriver crate is deprecated and will be removed from opentelemetry-rust-contrib. Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

Returns true if value is a variant of FieldBehavior.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl FieldBehavior

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

Migrate to OTLP (Google Cloud supports OTLP ingestion, and the OpenTelemetry Collector ships a googlecloud exporter). See https://github.com/open-telemetry/opentelemetry-rust-contrib/issues/609 for context.

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>
