Enum RefreshPolicy 

#[non_exhaustive]
pub enum RefreshPolicy {
    OnFlush,
    OnSeal,
    Periodic(u64),
    Manual,
}

When to refresh the aggregate.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OnFlush

Refresh on every memtable flush. Lowest latency.

OnSeal

Refresh when a partition is sealed. Lower CPU cost.

Periodic(u64)

Refresh every N milliseconds.

Manual

Only refresh via explicit REFRESH command.

Trait Implementations

impl Clone for RefreshPolicy

fn clone(&self) -> RefreshPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefreshPolicy

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

Formats the value using the given formatter.

impl Default for RefreshPolicy

fn default() -> RefreshPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RefreshPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for RefreshPolicy

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl PartialEq for RefreshPolicy

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

impl Serialize for RefreshPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for RefreshPolicy

fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the MessagePack representation of this value into the provided writer.
