Enum ReadLevel 

pub enum ReadLevel {
    IndexAndWal,
    IndexOnly,
    IndexAndBoundedWal,
}

Variants

IndexAndWal

Read from both the index and the write-ahead log (default). Provides full consistency with all committed writes visible.

IndexOnly

Read only from the index, skipping the write-ahead log. Provides eventual consistency - recent uncommitted writes may not be visible.

IndexAndBoundedWal

Read from the index and up to a server-configured number of write-ahead log entries. Provides a consistent prefix of the WAL with bounded query latency: recently committed writes beyond the limit may not be visible.

Trait Implementations

impl Clone for ReadLevel

fn clone(&self) -> ReadLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ReadLevel

impl Debug for ReadLevel

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

Formats the value using the given formatter.

impl Default for ReadLevel

fn default() -> ReadLevel

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ReadLevel

fn deserialize<__D>( __deserializer: __D, ) -> Result<ReadLevel, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ReadLevel

impl From<ReadLevel> for ReadLevel

fn from(value: ReadLevel) -> ReadLevel

Converts to this type from the input type.

impl PartialEq for ReadLevel

fn eq(&self, other: &ReadLevel) -> 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 ReadLevel

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
