Create or open a database:
-
- db, err := leveldb.OpenFile("path/to/db", nil)
- ...
- defer db.Close()
- ...
-
+```go
+db, err := leveldb.OpenFile("path/to/db", nil)
+...
+defer db.Close()
+...
+```
Read or modify the database content:
-
- // Remember that the contents of the returned slice should not be modified.
- data, err := db.Get([]byte("key"), nil)
- ...
- err = db.Put([]byte("key"), []byte("value"), nil)
- ...
- err = db.Delete([]byte("key"), nil)
- ...
+```go
+// Remember that the contents of the returned slice should not be modified.
+data, err := db.Get([]byte("key"), nil)
+...
+err = db.Put([]byte("key"), []byte("value"), nil)
+...
+err = db.Delete([]byte("key"), nil)
+...
+```
Iterate over database content:
-
- iter := db.NewIterator(nil, nil)
- for iter.Next() {
- // Remember that the contents of the returned slice should not be modified, and
- // only valid until the next call to Next.
- key := iter.Key()
- value := iter.Value()
- ...
- }
- iter.Release()
- err = iter.Error()
+```go
+iter := db.NewIterator(nil, nil)
+for iter.Next() {
+ // Remember that the contents of the returned slice should not be modified, and
+ // only valid until the next call to Next.
+ key := iter.Key()
+ value := iter.Value()
...
-
+}
+iter.Release()
+err = iter.Error()
+...
+```
Seek-then-Iterate:
-
- iter := db.NewIterator(nil, nil)
- for ok := iter.Seek(key); ok; ok = iter.Next() {
- // Use key/value.
- ...
- }
- iter.Release()
- err = iter.Error()
+```go
+iter := db.NewIterator(nil, nil)
+for ok := iter.Seek(key); ok; ok = iter.Next() {
+ // Use key/value.
...
-
+}
+iter.Release()
+err = iter.Error()
+...
+```
Iterate over subset of database content:
-
- iter := db.NewIterator(&util.Range{Start: []byte("foo"), Limit: []byte("xoo")}, nil)
- for iter.Next() {
- // Use key/value.
- ...
- }
- iter.Release()
- err = iter.Error()
+```go
+iter := db.NewIterator(&util.Range{Start: []byte("foo"), Limit: []byte("xoo")}, nil)
+for iter.Next() {
+ // Use key/value.
...
-
+}
+iter.Release()
+err = iter.Error()
+...
+```
Iterate over subset of database content with a particular prefix:
-
- iter := db.NewIterator(util.BytesPrefix([]byte("foo-")), nil)
- for iter.Next() {
- // Use key/value.
- ...
- }
- iter.Release()
- err = iter.Error()
+```go
+iter := db.NewIterator(util.BytesPrefix([]byte("foo-")), nil)
+for iter.Next() {
+ // Use key/value.
...
-
+}
+iter.Release()
+err = iter.Error()
+...
+```
Batch writes:
-
- batch := new(leveldb.Batch)
- batch.Put([]byte("foo"), []byte("value"))
- batch.Put([]byte("bar"), []byte("another value"))
- batch.Delete([]byte("baz"))
- err = db.Write(batch, nil)
- ...
-
+```go
+batch := new(leveldb.Batch)
+batch.Put([]byte("foo"), []byte("value"))
+batch.Put([]byte("bar"), []byte("another value"))
+batch.Delete([]byte("baz"))
+err = db.Write(batch, nil)
+...
+```
Use bloom filter:
-
- o := &opt.Options{
- Filter: filter.NewBloomFilter(10),
- }
- db, err := leveldb.OpenFile("path/to/db", o)
- ...
- defer db.Close()
- ...
-
+```go
+o := &opt.Options{
+ Filter: filter.NewBloomFilter(10),
+}
+db, err := leveldb.OpenFile("path/to/db", o)
+...
+defer db.Close()
+...
+```
