Struct mz_adapter::coord::read_policy::ReadCapability
source · pub(crate) struct ReadCapability<T = Timestamp>where
T: Timestamp,{
pub(crate) base_policy: ReadPolicy<T>,
pub(crate) 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§
source§impl<T: Timestamp> ReadCapability<T>
impl<T: Timestamp> ReadCapability<T>
sourcepub(crate) fn policy(&self) -> ReadPolicy<T>
pub(crate) fn policy(&self) -> ReadPolicy<T>
Acquires the effective read policy, reflecting both the base policy and any holds.
