Types ¶
type FilePrint ¶
type FilePrint struct {
// contains filtered or unexported fields
}
FilePrint represents a sort of "fingerprint" for a file in memory.
Mainly, it stores the path of the file, it's size, and a hash of the file. That last one is computed lazily (only when requested, and only once), in a thread-safe way.
func NewFilePrint ¶
func NewFilePrint(path string, size int64, pool *HashingPool) *FilePrint
NewFilePrint creates a new FilePrint.
type FilePrintSlice ¶
type FilePrintSlice []*FilePrint
FilePrintSlice is a simple slice of pointers to FilePrints.
Mostly to implement the sort.Interface, with the path as the ID.
func (FilePrintSlice) Len ¶
func (fps FilePrintSlice) Len() int
func (FilePrintSlice) Less ¶
func (fps FilePrintSlice) Less(i, j int) bool
func (FilePrintSlice) Swap ¶
func (fps FilePrintSlice) Swap(i, j int)
type HashingPool ¶
type HashingPool struct {
// contains filtered or unexported fields
}
HashingPool implements a thread-safe pools of useful resources when doing hashing.
func NewHashingPool ¶
func NewHashingPool(bufferSize int) *HashingPool
NewHashingPool creates a new HashingPool.
bufferSize specifies the size of the buffers it will return.
func (*HashingPool) GetBuffer ¶
func (hp *HashingPool) GetBuffer() *[]byte
GetBuffer returns a buffer from the pool, creating it if there isn't any.
func (*HashingPool) GetHasher ¶
func (hp *HashingPool) GetHasher() hash.Hash
GetHasher returns a buffer from the pool, creating it if there isn't any.
func (*HashingPool) PutBuffer ¶
func (hp *HashingPool) PutBuffer(buffer *[]byte)
PutBuffer puts a buffer back int the pool.
Should be called when done with the buffer.
func (*HashingPool) PutHasher ¶
func (hp *HashingPool) PutHasher(hasher hash.Hash)
PutBuffer puts a hasher back int the pool, and resets it.
Should be called when done with the hasher.
