Enum pagecache::SegmentMode

pub enum SegmentMode {
    Linear,
    Gc,
}

The log may be configured to write data in several different ways, depending on the constraints of the system using it.

Variants

Linear

Write to the end of the log, always.

Gc

Keep track of segment utilization, and reuse segments when their contents are fully relocated elsewhere. Will try to copy data out of segments once they reach a configurable threshold.

Trait Implementations

impl PartialEq<SegmentMode> for SegmentMode

fn eq(&self, other: &SegmentMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for SegmentMode

fn clone(&self) -> SegmentMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SegmentMode

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

Formats the value using the given formatter.

impl Serialize for SegmentMode

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

Serialize this value into the given Serde serializer.

impl<'de> Deserialize<'de> for SegmentMode

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

Deserialize this value from the given Serde deserializer.
