Implementations

impl<T: ThreadMode> DBWithThreadMode<T>

Methods of DBWithThreadMode.

pub fn open_default<P: AsRef<Path>>(path: P) -> Result<Self, Error>

Opens a database with default options.

pub fn open<P: AsRef<Path>>(opts: &Options, path: P) -> Result<Self, Error>

Opens the database with the specified options.

pub fn open_for_read_only<P: AsRef<Path>>( opts: &Options, path: P, error_if_log_file_exist: bool, ) -> Result<Self, Error>

Opens the database for read only with the specified options.

pub fn open_as_secondary<P: AsRef<Path>>( opts: &Options, primary_path: P, secondary_path: P, ) -> Result<Self, Error>

Opens the database as a secondary.

pub fn open_with_ttl<P: AsRef<Path>>( opts: &Options, path: P, ttl: Duration, ) -> Result<Self, Error>

Opens the database with a Time to Live compaction filter.

This applies the given ttl to all column families created without an explicit TTL. See DB::open_cf_descriptors_with_ttl for more control over individual column family TTLs.

pub fn open_cf_with_ttl<P, I, N>( opts: &Options, path: P, cfs: I, ttl: Duration, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = N>, N: AsRef<str>,

Opens the database with a Time to Live compaction filter and column family names.

Column families opened using this function will be created with default Options.

pub fn open_cf_descriptors_with_ttl<P, I>( opts: &Options, path: P, cfs: I, ttl: Duration, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = ColumnFamilyDescriptor>,

Opens a database with the given database with a Time to Live compaction filter and column family descriptors.

Applies the provided ttl as the default TTL for all column families. Column families will inherit this TTL by default, unless their descriptor explicitly sets a different TTL using ColumnFamilyTtl::Duration or opts out using ColumnFamilyTtl::Disabled.

NOTE: The default column family is opened with Options::default() unless explicitly configured within the cfs iterator. To customize the default column family’s options, include a ColumnFamilyDescriptor with the name “default” in the cfs iterator.

If you want to open default cf with different options, set them explicitly in cfs.

pub fn open_cf<P, I, N>(opts: &Options, path: P, cfs: I) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = N>, N: AsRef<str>,

Opens a database with the given database options and column family names.

Column families opened using this function will be created with default Options.

pub fn open_cf_with_opts<P, I, N>( opts: &Options, path: P, cfs: I, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = (N, Options)>, N: AsRef<str>,

Opens a database with the given database options and column family names.

Column families opened using given Options.

pub fn open_cf_for_read_only<P, I, N>( opts: &Options, path: P, cfs: I, error_if_log_file_exist: bool, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = N>, N: AsRef<str>,

Opens a database for read only with the given database options and column family names. NOTE: default column family is opened with Options::default(). If you want to open default cf with different options, set them explicitly in cfs.

pub fn open_cf_with_opts_for_read_only<P, I, N>( db_opts: &Options, path: P, cfs: I, error_if_log_file_exist: bool, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = (N, Options)>, N: AsRef<str>,

Opens a database for read only with the given database options and column family names. NOTE: default column family is opened with Options::default(). If you want to open default cf with different options, set them explicitly in cfs.

pub fn open_cf_descriptors_read_only<P, I>( opts: &Options, path: P, cfs: I, error_if_log_file_exist: bool, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = ColumnFamilyDescriptor>,

Opens a database for ready only with the given database options and column family descriptors. NOTE: default column family is opened with Options::default(). If you want to open default cf with different options, set them explicitly in cfs.

pub fn open_cf_as_secondary<P, I, N>( opts: &Options, primary_path: P, secondary_path: P, cfs: I, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = N>, N: AsRef<str>,

Opens the database as a secondary with the given database options and column family names. NOTE: default column family is opened with Options::default(). If you want to open default cf with different options, set them explicitly in cfs.

pub fn open_cf_descriptors_as_secondary<P, I>( opts: &Options, path: P, secondary_path: P, cfs: I, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = ColumnFamilyDescriptor>,

Opens the database as a secondary with the given database options and column family descriptors. NOTE: default column family is opened with Options::default(). If you want to open default cf with different options, set them explicitly in cfs.

pub fn open_cf_descriptors<P, I>( opts: &Options, path: P, cfs: I, ) -> Result<Self, Error>

where P: AsRef<Path>, I: IntoIterator<Item = ColumnFamilyDescriptor>,

Opens a database with the given database options and column family descriptors. NOTE: default column family is opened with Options::default(). If you want to open default cf with different options, set them explicitly in cfs.

pub fn delete_range_cf_opt<K: AsRef<[u8]>>( &self, cf: &impl AsColumnFamilyRef, from: K, to: K, writeopts: &WriteOptions, ) -> Result<(), Error>
