Struct SizeApproximationFlags 

pub struct SizeApproximationFlags(/* private fields */);

Which kinds of data DB::get_approximate_sizes_cf_with_flags counts.

This is the older flag-based form of SizeApproximationOptions, kept because it is the only variant RocksDB exposes for a single column family without allocating an options object. It cannot express an error margin.

Implementations

impl SizeApproximationFlags

pub const NONE: Self

Count nothing, which makes every returned size zero.

pub const INCLUDE_MEMTABLE: Self

Count data still in the memtables.

pub const INCLUDE_FILES: Self

Count data in SST files.

pub const INCLUDE_BLOB_FILES: Self

Count a prorated share of the blob files, as described on SizeApproximationOptions::set_include_blob_files.
