Enum CredentialState 

pub enum CredentialState {
    Fresh,
    RefreshWindow,
    Grace,
    Expired,
}

Lifecycle state of a cached credential.

Variants

Fresh

Credential is within its primary validity period. Serve directly.

RefreshWindow

Credential is aging — a background refresh should be attempted, but the cached value can still be served if refresh fails.

Grace

Credential is past the refresh window but within the grace period. Serve the stale value as a last resort while re-acquisition is attempted.

Expired

Credential has fully expired. Must re-acquire from the external source.

Trait Implementations

impl Clone for CredentialState

fn clone(&self) -> CredentialState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CredentialState

impl Debug for CredentialState

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

impl Eq for CredentialState

impl PartialEq for CredentialState

fn eq(&self, other: &CredentialState) -> 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.
