Struct BucketStats

pub struct BucketStats { /* private fields */ }

BucketStats records statistics about resources used by a bucket.

Implementations

impl BucketStats

pub fn branch_page_n(&self) -> i64

number of logical branch pages

pub fn branch_overflow_n(&self) -> i64

number of physical branch overflow pages

pub fn leaf_page_n(&self) -> i64

number of logical leaf pages

pub fn leaf_overflow_n(&self) -> i64

number of physical leaf overflow pages

pub fn key_n(&self) -> i64

number of keys/value pairs

pub fn depth(&self) -> i64

number of levels in B+tree

pub fn branch_alloc(&self) -> i64

bytes allocated for physical branch pages

pub fn branch_in_use(&self) -> i64

bytes actually used for branch data

pub fn leaf_alloc(&self) -> i64

bytes allocated for physical leaf pages

pub fn leaf_in_use(&self) -> i64

bytes actually used for leaf data

pub fn bucket_n(&self) -> i64

total number of buckets including the top bucket

pub fn inline_bucket_n(&self) -> i64

total number on inlined buckets

pub fn inline_bucket_in_use(&self) -> i64

bytes used for inlined buckets (also accounted for in LeafInuse)

Trait Implementations

impl AddAssign for BucketStats

fn add_assign(&mut self, rhs: BucketStats)

Performs the += operation.

impl Clone for BucketStats

fn clone(&self) -> BucketStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BucketStats

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

Formats the value using the given formatter.

impl Default for BucketStats

fn default() -> BucketStats

Returns the “default value” for a type.

impl PartialEq for BucketStats

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