Methods

impl Gdbm

fn new(
    path: &Path,
    block_size: u32,
    flags: Flags,
    mode: i32
) -> Result<Gdbm, GdbmError>

Open a DBM with location. mode (see http://www.manpagez.com/man/2/chmod, and http://www.manpagez.com/man/2/open), which is used if the file is created).

fn store(&self, key: &str, content: &mut String, flag: StoreFlags) -> i32

This function returns either -1, 0 or +1. -1 means the item was not stored. 0 means it was stored and +1 means it was not stored because the key already existed. See the link below for more details. http://www.gnu.org.ua/software/gdbm/manual/gdbm.html#Store

fn fetch(&self, key: &str) -> Result<String, GdbmError>

Retrieve a key from the database

fn delete(&self, key: &str) -> bool

Delete a key and value from the database

fn sync(&self)

fn exists(&self, key: &str) -> Result<bool, GdbmError>

Check to see if a key exists in the database

fn fdesc(&self) -> c_int

With locking disabled (if gdbm_open was called with ‘GDBM_NOLOCK’), the user may want to perform their own file locking on the database file in order to prevent multiple writers operating on the same file simultaneously.
