Enum CompactionLevel 

pub enum CompactionLevel {
    Raw = 0,
    Daily = 1,
    Weekly = 2,
    Monthly = 3,
    Root = 4,
}

Compaction level in the compression hierarchy.

Variants

Raw = 0

Raw session data (uncompressed).

Daily = 1

Daily summary (compressed from raw).

Weekly = 2

Weekly summary (compressed from weekly).

Monthly = 3

Monthly summary (compressed from weekly).

Root = 4

Root index entry (top-level summary).

Implementations

impl CompactionLevel

pub fn threshold(&self) -> usize

Line count threshold for triggering compaction at this level.

When content at this level exceeds the threshold, it becomes a candidate for promotion to the next level.

pub fn dir_name(&self) -> &'static str

Storage subdirectory name for this level.

pub fn all() -> &'static [CompactionLevel]

All levels in ascending order.

pub fn next(&self) -> Option<CompactionLevel>

Get the next higher compaction level.

Returns None for Root (topmost level).

pub fn as_u8(&self) -> u8

Numeric value of this level.

pub fn from_u8(v: u8) -> Option<Self>

Try to convert a u8 to a CompactionLevel.

Trait Implementations

impl Clone for CompactionLevel

fn clone(&self) -> CompactionLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CompactionLevel

impl Debug for CompactionLevel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompactionLevel

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CompactionLevel

impl Ord for CompactionLevel

fn cmp(&self, other: &CompactionLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CompactionLevel

fn eq(&self, other: &CompactionLevel) -> 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 PartialOrd for CompactionLevel

fn partial_cmp(&self, other: &CompactionLevel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for CompactionLevel

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
