Enum FlushPolicy 

pub enum FlushPolicy {
    Immediate,
    Batch {
        threshold: usize,
        interval_ms: u64,
    },
}

Controls when in-memory logs should be flushed to disk.

Variants

Immediate

Flush each log write immediately to disk.

• Guarantees the highest durability.
• Each append operation causes a disk write.

Batch

Flush entries to disk when either of two conditions is met:

• The number of unflushed entries reaches the given threshold.

• The elapsed time since the last flush exceeds the configured interval.

• Balances performance and durability.

• Recent unflushed entries may be lost in the event of a crash or power failure.

Fields

threshold: usize

interval_ms: u64

Trait Implementations

impl Clone for FlushPolicy

fn clone(&self) -> FlushPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlushPolicy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FlushPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FlushPolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
