Struct FileStatisticsCacheEntry 

pub struct FileStatisticsCacheEntry {
    pub object_meta: ObjectMeta,
    pub num_rows: Precision<usize>,
    pub num_columns: usize,
    pub table_size_bytes: Precision<usize>,
    pub statistics_size_bytes: usize,
}

Represents information about a cached statistics entry. This is used to expose the statistics cache contents to outside modules.

Fields

object_meta: ObjectMeta

num_rows: Precision<usize>

Number of table rows.

num_columns: usize

Number of table columns.

table_size_bytes: Precision<usize>

Total table size, in bytes.

statistics_size_bytes: usize

Size of the statistics entry, in bytes.

Trait Implementations

impl Clone for FileStatisticsCacheEntry

fn clone(&self) -> FileStatisticsCacheEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileStatisticsCacheEntry

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

Formats the value using the given formatter.

impl PartialEq for FileStatisticsCacheEntry

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