Enum GcsCredentials 

pub enum GcsCredentials {
    ServiceAccountJsonFile {
        path: String,
    },
    ServiceAccountJsonInline {
        json: String,
    },
    ApplicationDefault,
    Anonymous,
}

Available on crate features source-gcs and source-rest only.

Credential source for a GCS client.

Serializes as { type: <method>, config: { … } } (adjacent tagging, snake_case discriminators) — the consistent auth wire shape shared by every faucet connector: { type: service_account_json_file, config: { path: "/run/secrets/sa.json" } }.

Variants

ServiceAccountJsonFile

Path to a service-account JSON key file on disk.

Fields

path: String

ServiceAccountJsonInline

Service-account JSON key as an inline string. Useful for environment-variable injection via ${env:GCP_SA_JSON} in CLI configs.

Fields

json: String

ApplicationDefault

Application Default Credentials — honours GOOGLE_APPLICATION_CREDENTIALS, gcloud user creds, and the GCE/GKE metadata server, in that order.

Anonymous

Anonymous credentials. Use this with emulators (e.g. fake-gcs-server) that do not validate bearer tokens — the SDK otherwise tries to fetch ADC tokens at request time and fails in environments without GCP credentials.

Trait Implementations

impl Clone for GcsCredentials

fn clone(&self) -> GcsCredentials

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GcsCredentials

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

Formats the value using the given formatter.

impl Default for GcsCredentials

fn default() -> GcsCredentials

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GcsCredentials

fn deserialize<__D>( __deserializer: __D, ) -> Result<GcsCredentials, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for GcsCredentials

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for GcsCredentials

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
