Struct TemporaryCredentialClient 

pub struct TemporaryCredentialClient { /* private fields */ }

Client for vending temporary storage credentials for tables, volumes, and paths.

Wraps the generated low-level client with name → UUID resolution: callers may pass a fully qualified name or a UUID, and the client issues the lookup needed to obtain the ID the credential endpoint requires. Prefer UnityCatalogClient::temporary_credentials.

Implementations

impl TemporaryCredentialClient

pub fn new_with_url(client: Transport, base_url: Url) -> Self

Creates a client from the per-target Transport (carrying auth) and a base URL.

The base URL is normalized to end in / so it joins cleanly with the relative endpoint paths.

pub fn new(client: TemporaryCredentialClientBase) -> Self

Creates a client wrapping an existing generated low-level client.

pub async fn temporary_table_credential( &self, table: impl Into<TableReference>, operation: TableOperation, ) -> Result<(TemporaryCredential, Uuid)>

Gets a temporary credential for reading or writing to a table.

Arguments

• table: The table to get a temporary credential for.
• operation: The operation to perform on the table.

Returns a tuple of the temporary credential and the resolved table ID.

pub async fn temporary_path_credential( &self, path: impl IntoUrl, operation: PathOperation, dry_run: impl Into<Option<bool>>, ) -> Result<(TemporaryCredential, Url)>

Gets a temporary credential for reading or writing to a storage path.

Pass dry_run to validate access without vending a usable credential. Returns a tuple of the temporary credential and the parsed path URL.

pub async fn temporary_volume_credential( &self, volume: impl Into<VolumeReference>, operation: VolumeOperation, ) -> Result<(TemporaryCredential, Uuid)>

Gets a temporary credential for reading or writing to a volume.

Arguments

• volume: The volume to get a temporary credential for. May be either a VolumeReference::Id (UUID, preferred when known) or a VolumeReference::Name in three-level dotted form (catalog.schema.volume). Names are resolved to IDs by issuing a GetVolume request.
• operation: Whether the credentials should grant read-only or read-write access.

Returns a tuple of the temporary credential and the resolved volume ID.

The Unity Catalog metastore must have external_access_enabled = true and the caller must hold EXTERNAL_USE_SCHEMA on the parent schema.

pub async fn temporary_model_version_credential( &self, full_name: impl Into<String>, version: i64, operation: ModelVersionOperation, ) -> Result<TemporaryCredential>

Gets a temporary credential for reading or writing to a model version.

Arguments

• full_name: The three-level (catalog.schema.model) name of the parent registered model.
• version: The integer version number of the model version.
• operation: Whether the credentials should grant read-only or read-write access.

The Unity Catalog metastore must have external_access_enabled = true and the caller must hold EXTERNAL_USE_SCHEMA on the parent schema.

Trait Implementations

impl Clone for TemporaryCredentialClient

fn clone(&self) -> TemporaryCredentialClient

Returns a duplicate of the value.

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

Performs copy-assignment from source.
