Types

type Decoder

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

func NewDecoder

func NewDecoder(pkg string, raw map[string]any) *Decoder

NewDecoder returns a new Decoder. raw should be decoded by the json package.

func (*Decoder) Decode

func (d *Decoder) Decode(s string, name string) []byte

Decode decodes s as base64 raw url encoding. the returned slice is valid until next call.

func (*Decoder) Err

func (d *Decoder) Err() error

Err returns the first error during decoding.

func (*Decoder) GetArray

func (d *Decoder) GetArray(name string) ([]any, bool)

GetArray gets an array parameter. If the parameter doesn't exist, it returns (nil, false).

func (*Decoder) GetBigInt

func (d *Decoder) GetBigInt(name string) (*big.Int, bool)

GetBigInt gets a big integer parameter. The parameter must be base64-raw-url encoded and big endian. If the parameter doesn't exist, it returns (nil, false).

func (*Decoder) GetBytes

func (d *Decoder) GetBytes(name string) ([]byte, bool)

GetBytes gets a parameter of byte sequence base64-raw-url encoded. If the parameter doesn't exist, it returns (nil, false).

func (*Decoder) GetInt64

func (d *Decoder) GetInt64(name string) (int64, bool)

GetInt64 gets an integer parameter. If the parameter doesn't exist, it returns (0, false).

func (*Decoder) GetObject

func (d *Decoder) GetObject(name string) (map[string]any, bool)

GetArray gets an object parameter. If the parameter doesn't exist, it returns (nil, false).

func (*Decoder) GetString

func (d *Decoder) GetString(name string) (string, bool)

GetString gets a string parameter. If the parameter doesn't exist, it returns ("", false).

func (*Decoder) GetStringArray

func (d *Decoder) GetStringArray(name string) ([]string, bool)

GetArray gets a string array parameter. If the parameter doesn't exist, it returns (nil, false).

func (*Decoder) GetTime

func (d *Decoder) GetTime(name string) (time.Time, bool)

GetTime gets a time parameter. The parameter must be a JSON number from UNIX time epoch in seconds. If the parameter doesn't exist, it returns (time.Time{}, false).

func (*Decoder) GetURL

func (d *Decoder) GetURL(name string) (*url.URL, bool)

GetURL gets a url parameter. If the parameter doesn't exist, it returns (nil, false).

func (*Decoder) Has

func (d *Decoder) Has(name string) bool

Has returns whether name parameter exists.

func (*Decoder) MustArray

func (d *Decoder) MustArray(name string) []any

MustArray gets an array parameter. If the parameter doesn't exist, it returns nil and save the error.

func (*Decoder) MustBigInt

func (d *Decoder) MustBigInt(name string) *big.Int

MustBigInt gets a big integer parameter. The parameter must be base64-raw-url encoded and big endian. If the parameter doesn't exist, it returns nil and save the error.

func (*Decoder) MustBytes

func (d *Decoder) MustBytes(name string) []byte

MustBytes gets a parameter of byte sequence base64-raw-url encoded. If the parameter doesn't exist, it returns nil and save the error.

func (*Decoder) MustInt64

func (d *Decoder) MustInt64(name string) int64

MustInt64 gets an integer parameter. If the parameter doesn't exist, it returns nil and save the error.

func (*Decoder) MustString

func (d *Decoder) MustString(name string) string

MustString gets a string parameter. If the parameter doesn't exist, it returns an empty string and save the error.

func (*Decoder) SaveError

func (d *Decoder) SaveError(err error)

SaveError asserts the operation must not fail. If err is nil, SaveError does nothing. Otherwise, SaveError records the first error.

type Encoder

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

func NewEncoder

func NewEncoder(raw map[string]any) *Encoder

func (*Encoder) Data

func (e *Encoder) Data() map[string]any

func (*Encoder) Encode

func (e *Encoder) Encode(s []byte) string

func (*Encoder) Err

func (e *Encoder) Err() error

func (*Encoder) SaveError

func (e *Encoder) SaveError(err error)

SaveError asserts the operation must not fail. If err is nil, SaveError does nothing. Otherwise, SaveError records the first error.

func (*Encoder) Set

func (e *Encoder) Set(name string, v any)

func (*Encoder) SetBigInt

func (e *Encoder) SetBigInt(name string, i *big.Int)

func (*Encoder) SetBytes

func (e *Encoder) SetBytes(name string, data []byte)

func (*Encoder) SetFixedBigInt

func (e *Encoder) SetFixedBigInt(name string, i *big.Int, size int)

func (*Encoder) SetTime

func (e *Encoder) SetTime(name string, t time.Time)

type NumericDate

type NumericDate struct {
	time.Time
}

NumericDate represents a JSON numeric date value defined in RFC 7519 Section 2.

func (NumericDate) MarshalJSON

func (date NumericDate) MarshalJSON() (b []byte, err error)

func (*NumericDate) UnmarshalJSON

func (date *NumericDate) UnmarshalJSON(b []byte) (err error)
