Struct VcDerivationEpochDeletion 

Source 
pub struct VcDerivationEpochDeletion { /* private fields */ }
Available on crate feature virtual-clients-draft and (32-bit or 64-bit) only.
Expand description

Selects the derivation epochs MlsGroup::delete_vc_derivation_epochs() deletes: those superseded before a point in time, optionally capped to a number of surviving epochs. An epoch is superseded when the next one is registered. The newest epoch is never selected.

Implementations§

Source§

impl VcDerivationEpochDeletion

Source

pub fn older_than_duration(duration: Duration) -> Self

Source

pub fn before_timestamp(timestamp: SystemTime) -> Self

Delete all derivation epochs superseded before timestamp.

Source

pub fn max_epochs(self, max_epochs: usize) -> Self

Additionally cap the number of derivation epochs that survive.
