Struct rocks::table_properties::TableProperties

#[repr(C)]pub struct TableProperties<'a> { /* fields omitted */ }

TableProperties contains a bunch of read-only properties of its associated table.

Implementations

impl<'a> TableProperties<'a>

pub fn data_size(&self) -> u64

the total size of all data blocks.

pub fn index_size(&self) -> u64

the size of index block.

pub fn filter_size(&self) -> u64

the size of filter block.

pub fn raw_key_size(&self) -> u64

total raw key size

pub fn raw_value_size(&self) -> u64

total raw value size

pub fn num_data_blocks(&self) -> u64

the number of blocks in this table

pub fn num_entries(&self) -> u64

the number of entries in this table

pub fn format_version(&self) -> u64

format version, reserved for backward compatibility

pub fn fixed_key_len(&self) -> u64

If 0, key is variable length. Otherwise number of bytes for each key.

pub fn column_family_id(&self) -> u32

ID of column family for this SST file, corresponding to the CF identified by column_family_name.

pub fn column_family_name(&self) -> Option<&str>

Name of the column family with which this SST file is associated. If column family is unknown, column_family_name will be an empty string.

pub fn filter_policy_name(&self) -> Option<&str>

The name of the filter policy used in this table. If no filter policy is used, filter_policy_name will be an empty string.

pub fn comparator_name(&self) -> &str

The name of the comparator used in this table.

pub fn merge_operator_name(&self) -> Option<&str>

The name of the merge operator used in this table. If no merge operator is used, merge_operator_name will be "nullptr".

pub fn prefix_extractor_name(&self) -> Option<&str>

The name of the prefix extractor used in this table If no prefix extractor is used, prefix_extractor_name will be "nullptr".

pub fn property_collectors_names(&self) -> &str

The names of the property collectors factories used in this table separated by commas {collector_name[1]},{collector_name[2]},{collector_name[3]} .. or []

pub fn compression_name(&self) -> &str

The compression algo used to compress the SST files.

pub fn user_collected_properties(&self) -> &UserCollectedProperties

user collected properties

pub fn readable_properties(&self) -> &UserCollectedProperties
