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_func(func: PythonFunction) -> Self

Available on crate feature python only.

pub fn from_python_func_object(func: PyObject) -> Self

Available on crate feature python only.
