Enum ScanFilter 

pub enum ScanFilter {
    All,
    OnlyAbnormal,
    OnlyAbnormalWithVerify,
    OnlyAbnormalTest,
}

which accounts scan should load from disk

Variants

All

Scan both in-memory and on-disk index

OnlyAbnormal

abnormal = ref_count != 1 or slot list.len() != 1 Scan only in-memory index and skip on-disk index

OnlyAbnormalWithVerify

Similar to `OnlyAbnormal but also check on-disk index to verify the entry on-disk is indeed normal.

OnlyAbnormalTest

Similar to `OnlyAbnormal but mark entries in memory as not found if they are normal This removes the possibility of any race conditions with index flushing and simulates the system running an uncached disk index where nothing ‘normal’ is ever held in the in memory index as far as callers are concerned. This could also be a correct/ideal future api to similarly provide consistency and remove race condition behavior.

Trait Implementations

impl Clone for ScanFilter

fn clone(&self) -> ScanFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScanFilter

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

Formats the value using the given formatter.

impl Default for ScanFilter

fn default() -> ScanFilter

Returns the “default value” for a type.

impl PartialEq for ScanFilter

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