Types ¶
type IBatch ¶
type IBatch interface {
IDatabasePutter
ValueSize() int // amount of data in the batch
Write() error
Reset() // Reset resets the batch for reuse
}
Batch is a write-only database that commits changes to its host database when Write is called. Batch cannot be used concurrently.
func NewTableBatch ¶
NewTableBatch returns a Batch object which prefixes all keys with a given string.
type IDatabase ¶
type IDatabase interface {
IDatabaseGetter
IDatabasePutter
Has(key []byte) (bool, error)
Delete(key []byte) error
Close()
NewBatch() IBatch
}
Database wraps all database operations. All methods are safe for concurrent use.
type IDatabaseGetter ¶
type IDatabasePutter ¶
type LDatabase ¶
type LDatabase struct {
// contains filtered or unexported fields
}
database struct
func (*LDatabase) NewIterator ¶

type MemDatabase struct {
// contains filtered or unexported fields
}
This is a test memory database. Do not use for any production it does not get persisted
