Enum DeltaCredentials 

pub enum DeltaCredentials {
    Default,
    Aws(AwsCredentials),
    Azure(AzureCredentials),
    Gcp(GcpCredentials),
}

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

Object-store credentials for reading/writing a Delta table.

Uses the project-wide adjacently-tagged { type, config } shape (snake_case discriminators): e.g. credentials: { type: aws, config: { … } }. The default is DeltaCredentials::Default, which resolves credentials from the ambient environment / instance metadata via the object-store default provider chain — nothing is injected into storage_options.

Variants

Default

Resolve credentials from the ambient environment / default provider chain (AWS instance profile, AZURE_* env, GCP ADC, …). Injects no keys of its own.

Aws(AwsCredentials)

Static AWS credentials (or an S3-compatible endpoint such as MinIO).

Azure(AzureCredentials)

Azure Blob / ADLS Gen2 credentials.

Gcp(GcpCredentials)

Google Cloud Storage credentials.

Implementations

impl DeltaCredentials

pub fn apply(&self, options: &mut HashMap<String, String>)

Merge the credential-derived keys into options, without overwriting any key the user set explicitly. This makes explicit storage_options authoritative — an escape hatch for keys this enum does not model.

pub fn storage_options(&self) -> HashMap<String, String>

The storage_options entries implied by these credentials.

Trait Implementations

impl Clone for DeltaCredentials

fn clone(&self) -> DeltaCredentials

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaCredentials

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

Formats the value using the given formatter.

impl Default for DeltaCredentials

fn default() -> DeltaCredentials

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DeltaCredentials

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DeltaCredentials

impl JsonSchema for DeltaCredentials

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 PartialEq for DeltaCredentials

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for DeltaCredentials

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.
