Struct cdb::CDB

pub struct CDB { /* private fields */ }

CDB file reader

Example

let cdb = cdb::CDB::open("tests/test1.cdb").unwrap();

for result in cdb.find(b"one") {
    println!("{:?}", result.unwrap());
}

Implementations

impl CDB

pub fn open<P: AsRef<Path>>(filename: P) -> Result<CDB>

Opens the named file and returns the CDB reader.

Examples

let cdb = cdb::CDB::open("tests/test1.cdb").unwrap();

pub fn get(&self, key: &[u8]) -> Option<Result<Vec<u8>>>

Find the first record with the named key.

Examples

let cdb = cdb::CDB::open("tests/test1.cdb").unwrap();
if let Some(record) = cdb.get(b"one") {
    println!("{:?}", record.unwrap());
}

pub fn find(&self, key: &[u8]) -> CDBValueIter<'_>

Find all records with the named key. The returned iterator produces each value associated with the key.

Examples

let cdb = cdb::CDB::open("tests/test1.cdb").unwrap();

for result in cdb.find(b"one") {
    println!("{:?}", result.unwrap());
}

pub fn iter(&self) -> CDBKeyValueIter<'_>

Iterate over all the (key, value) pairs in the database.

Examples

let cdb = cdb::CDB::open("tests/test1.cdb").unwrap();
for result in cdb.iter() {
    let (key, value) = result.unwrap();
    println!("{:?} => {:?}", key, value);
}
