Constants ¶
const MaxBruteForce = 64
const PrimeRK = 16777619
PrimeRK is the prime base used in Rabin-Karp algorithm.
Variables ¶
var MaxLen int
MaxLen is the maximum length of the string to be searched for (argument b) in Index. If MaxLen is not 0, make sure MaxLen >= 4.
Functions ¶
func CountString ¶
func Cutover ¶
Cutover reports the number of failures of IndexByte we should tolerate before switching over to Index. n is the number of bytes processed so far. See the bytes.Index implementation for details.
func Equal ¶
Equal reports whether a and b are the same length and contain the same bytes. A nil argument is equivalent to an empty slice.
Equal is equivalent to bytes.Equal. It is provided here for convenience, because some packages cannot depend on bytes.
func HashStr ¶ added in go1.15
HashStr returns the hash and the appropriate multiplicative factor for use in Rabin-Karp algorithm.
func HashStrBytes ¶ added in go1.15
HashStrBytes returns the hash and the appropriate multiplicative factor for use in Rabin-Karp algorithm.
func HashStrRev ¶ added in go1.15
HashStrRev returns the hash of the reverse of sep and the appropriate multiplicative factor for use in Rabin-Karp algorithm.
func HashStrRevBytes ¶ added in go1.15
HashStrRevBytes returns the hash of the reverse of sep and the appropriate multiplicative factor for use in Rabin-Karp algorithm.
func Index ¶
Index returns the index of the first instance of b in a, or -1 if b is not present in a. Requires 2 <= len(b) <= MaxLen.
func IndexByteString ¶
func IndexRabinKarp ¶ added in go1.15
IndexRabinKarp uses the Rabin-Karp search algorithm to return the index of the first occurrence of substr in s, or -1 if not present.
func IndexRabinKarpBytes ¶ added in go1.15
IndexRabinKarpBytes uses the Rabin-Karp search algorithm to return the index of the first occurrence of substr in s, or -1 if not present.
func IndexString ¶
IndexString returns the index of the first instance of b in a, or -1 if b is not present in a. Requires 2 <= len(b) <= MaxLen.
func MakeNoZero ¶ added in go1.21.0
MakeNoZero makes a slice of length and capacity n without zeroing the bytes. It is the caller's responsibility to ensure uninitialized bytes do not leak to the end user.
