Struct mz_coord::coord::ReadCapability
source · [−]struct ReadCapability<T = Timestamp> where
T: Timestamp, {
base_policy: ReadPolicy<T>,
holds: MutableAntichain<T>,
}Expand description
Information about the read capability requirements of a collection.
This type tracks both a default policy, as well as various holds that may be expressed, as by transactions to ensure collections remain readable.
Fields
base_policy: ReadPolicy<T>The default read policy for the collection when no holds are present.
holds: MutableAntichain<T>Holds expressed by transactions, that should prevent compaction.
Implementations
sourceimpl<T: Timestamp> ReadCapability<T>
impl<T: Timestamp> ReadCapability<T>
sourcefn policy(&self) -> ReadPolicy<T>
fn policy(&self) -> ReadPolicy<T>
Acquires the effective read policy, reflecting both the base policy and any holds.
