Enum PlCredentialProvider 

pub enum PlCredentialProvider {
    Function(CredentialProviderFunction),
    Python(PythonCredentialProvider),
}

Available on crate feature cloud only.

Variants

Function(CredentialProviderFunction)

Prefer using PlCredentialProvider::from_func instead of constructing this directly

Python(PythonCredentialProvider)

Available on crate feature python only.

Implementations

impl PlCredentialProvider

pub fn from_func( func: impl Fn() -> Pin<Box<dyn Future<Output = PolarsResult<(ObjectStoreCredential, u64)>> + Send + Sync>> + Send + Sync + 'static, ) -> Self

Accepts a function that returns (credential, expiry time as seconds since UNIX_EPOCH)

This functionality is unstable.

pub fn from_python_builder(func: Py<PyAny>) -> Self

Available on crate feature python only.

Intended to be called with an internal CredentialProviderBuilder from py-polars.

Trait Implementations

impl Clone for PlCredentialProvider

fn clone(&self) -> PlCredentialProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlCredentialProvider

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PlCredentialProvider

Available on crate feature serde only.

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PlCredentialProvider

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl IntoCredentialProvider for PlCredentialProvider

fn into_aws_provider(self) -> AwsCredentialProvider

Available on crate feature aws only.

fn into_azure_provider(self) -> AzureCredentialProvider

Available on crate feature azure only.

fn into_gcp_provider(self) -> GcpCredentialProvider

Available on crate feature gcp only.

fn storage_update_options(&self) -> PolarsResult<Vec<(PlSmallStr, PlSmallStr)>>

Note, technically shouldn’t be under the IntoCredentialProvider trait, but it’s here for convenience.

impl JsonSchema for PlCredentialProvider

Available on crate feature dsl-schema only.

fn schema_name() -> String

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 is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for PlCredentialProvider

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

Available on crate feature serde only.

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

where S: Serializer,

Serialize this value into the given Serde serializer.
