Types ¶
type Block ¶
type Block struct {
// contains filtered or unexported fields
}
Block is a buffer aligned with disk data block with two offset (left and right) representing the start and end of the effective payload inside the buffer
func (*Block) Copy ¶
Copy copies a byte array to the offset of the buffer It also updates the effective payload offsets
type BlockReaderStream ¶
type BlockReaderStream struct {
// contains filtered or unexported fields
}
func (*BlockReaderStream) NextBlock ¶
func (brs *BlockReaderStream) NextBlock() (*Block, error)
type BlockWriterStream ¶
type BlockWriterStream struct {
// contains filtered or unexported fields
}
func (*BlockWriterStream) NextBlock ¶
func (bws *BlockWriterStream) NextBlock() (*Block, error)
NextBlock gets the next block from the input stream
type Disk ¶
type Disk struct {
// Name is the name of the disk.
Name string
// Root is the root path of the disk
// Usually it is the mount point of a disk or a directory
// under the mount point.
Root string
}
