pub struct Stat(_);

Expand description

Environment statistics.

Contains information about the size and layout of an MDBX environment or database.

Implementations

source

impl Stat

source

pub fn page_size(&self) -> u32

Size of a database page. This is the same for all databases in the environment.

source

pub fn depth(&self) -> u32

Depth (height) of the B-tree.

source

pub fn branch_pages(&self) -> usize

Number of internal (non-leaf) pages.

source

pub fn leaf_pages(&self) -> usize

Number of leaf pages.

source

pub fn overflow_pages(&self) -> usize

Number of overflow pages.

source

pub fn entries(&self) -> usize

Number of data items.
