Types

type AsyncHash 

type AsyncHash interface {
	hash.Hash
	io.Closer
	Digest() Digest
	Done() <-chan Digest
}

AsyncHash is a wrapper for hash.Hash that operates asynchronously by using a buffering pipe to accept input and a channel to provide the final digest

func NewAsyncHash 

func NewAsyncHash(algorithm string, size int64) (AsyncHash, error)

NewAsyncHash returns an AsyncHash that implements the requested hash. Only some algorithms require knowing the size of the input first (git sha1).

type BasicHasher 

type BasicHasher struct {
	hash.Hash
	// contains filtered or unexported fields
}

BasicHasher is a hash.AsyncHasher that calculates a sha1sum using the same salting mechanism as git does when storing blob objects

func (BasicHasher) Close 

func (sh BasicHasher) Close() error

Close closes the underlying pipe and finalizes the hash

func (BasicHasher) Digest 

func (sh BasicHasher) Digest() Digest

Digest returns the calculated Digest. This consumes the channel returned by Done(), but will always return the same Digest afterwards.

func (BasicHasher) Done 

func (sh BasicHasher) Done() <-chan Digest

Done returns a Digest channel, satisfying the AsyncHasher interface

func (BasicHasher) Write 

func (sh BasicHasher) Write(bytes []byte) (int, error)

Write adds the given slice to the internal Hash

type Digest 

type Digest interface {
	// A Digest is a hash.Hash that has already been finalized and is
	// essentially a wrapper around the fixed length checksum result
	// hash.Hash
	Sum(b []byte) []byte
	// Reset()
	Size() int

	// IsZero returns true for Digests that are the zero-value of their type
	// (aka, all 0s)
	IsZero() bool

	// String returns the hex string representing the checksum
	String() string

	// Base64 returns the checksum as a base64 string
	Base64() string

	// Bytes returns the finalized checksum bytes, similar to Sum(), but
	// simplified for hashes that have already been finalized
	Bytes() []byte
}

Digest is a finalized hash.Hash. It conforms to the hash.Hash interface, but it does not support operations that modify the finalized checksum

type DigestMatcher 

type DigestMatcher struct {
	P string
	T string
	B []byte
}

DigestMatcher is a multi-hash comparison operand allowing Digest objects to be matched against.

func NewDigestMatcher 

func NewDigestMatcher(pat string) (DigestMatcher, error)

NewDigestMatcher creates a new DigestMatcher by parsing the provided string

func (DigestMatcher) Match 

func (matcher DigestMatcher) Match(hash Digest) bool

Match compares the DigestMatcher against a given Digest, either by string representation or direct byte comparison if the provided string was an even number of hex digits.

type GitShaDigest struct {
	// contains filtered or unexported fields
}

GitShaDigest is the variant of sha1 used by Git to identify blobs
