Enum PlCredentialProvider

pub enum PlCredentialProvider {
    Function(CredentialProviderFunction),
}

Available on crate features polars-io and cloud only.

Variants

Function(CredentialProviderFunction)

Prefer using PlCredentialProvider::from_func instead of constructing this directly

Implementations

impl PlCredentialProvider

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

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

This functionality is unstable.

Trait Implementations

impl Clone for PlCredentialProvider

fn clone(&self) -> PlCredentialProvider

Returns a copy 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<(), Error>

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<PlCredentialProvider, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PlCredentialProvider

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
