RawString reassembles the URL into a valid URL string without encoding any component.

func (*TxID) ShortString 

func (x *TxID) ShortString() string

ShortString returns String without the scheme prefix.

func (*TxID) String 

func (x *TxID) String() string

func (*TxID) UnmarshalJSON 

func (x *TxID) UnmarshalJSON(data []byte) error

UnmarshalJSON unmarshals the transaction ID from JSON as a string.

type URL 

type URL struct {
	UserInfo  string
	Authority string
	Path      string
	Query     string
	Fragment  string
	// contains filtered or unexported fields
}

URL is an Accumulate URL.

func MustParse 

func MustParse(s string) *URL

MustParse calls Parse and panics if it returns an error.

func Parse 

func Parse(s string) (*URL, error)

Parse parses the string as an Accumulate URL. The scheme may be omitted, in which case `acc://` will be added, but if present it must be `acc`. The hostname must be non-empty. RawPath, ForceQuery, and RawFragment are not preserved.

func (*URL) AccountID 

func (u *URL) AccountID() []byte

AccountID constructs an account identifier from the lower case hostname and path. The port is not included. If the path does not begin with `/`, `/` is added between the hostname and the path. 

ID = Hash(LowerCase(Sprintf("%s/%s", u.Host(), u.Path)))

func (*URL) AccountID32 

func (u *URL) AccountID32() [32]byte

AccountID32 returns AccountID as a [32]byte.

func (*URL) AsTxID 

func (u *URL) AsTxID() (*TxID, error)

AsTxID parses the URL's user info as a transaction hash.

func (*URL) Compare 

func (u *URL) Compare(v *URL) int

Compare returns an integer comparing two URLs as lower case strings. The result will be 0 if u == v, -1 if u < v, and +1 if u > v.

func (*URL) Equal 

func (u *URL) Equal(v *URL) bool

Equal reports whether u and v, converted to strings and interpreted as UTF-8, are equal under Unicode case-folding.

func (*URL) Hash 

func (u *URL) Hash() []byte

Hash calculates a hash of the URL starting with AccountID, hashing and concatenating Query unless it is empty, and hashing and concatenating Fragment unless it is empty. If Query and Fragment are both non-empty, with H defined as the SHA-256 hash of the lower case of the operand, the result is H(H(AccountID + H(Query)) + H(Fragment)).

func (*URL) Hash32 

func (u *URL) Hash32() [32]byte

Hash32 returns Hash as a [32]byte.

func (*URL) Hostname 

func (u *URL) Hostname() string

Hostname returns the hostname from the authority component.

func (*URL) Identity 

func (u *URL) Identity() *URL

Identity returns a copy of the URL with the last section cut off the path.

func (*URL) IdentityAccountID 

func (u *URL) IdentityAccountID() []byte

IdentityAccountID constructs an account identifier from the lower case hostname. The port is not included.
