package buffer

import "github.com/open-policy-agent/opa/internal/jwx/buffer"

Package buffer provides a very thin wrapper around []byte buffer called `Buffer`, to provide functionalities that are often used within the jwx related packages

Types ¶

type Buffer ¶

type Buffer []byte

Buffer wraps `[]byte` and provides functions that are often used in the jwx related packages. One notable difference is that while encoding/json marshalls `[]byte` using base64.StdEncoding, this module uses base64.RawURLEncoding as mandated by the spec

func FromBase64 ¶

func FromBase64(v []byte) (Buffer, error)

FromBase64 constructs a new Buffer from a base64 encoded data

func FromNData ¶

func FromNData(v []byte) (Buffer, error)

FromNData constructs a new Buffer from a "n:data" format (I made that name up)

func FromUint ¶

func FromUint(v uint64) Buffer

FromUint creates a `Buffer` from an unsigned int

func (*Buffer) Base64Decode ¶

func (b *Buffer) Base64Decode(v []byte) error

Base64Decode decodes the contents of the Buffer using base64.RawURLEncoding

func (Buffer) Base64Encode ¶

func (b Buffer) Base64Encode() ([]byte, error)

Base64Encode encodes the contents of the Buffer using base64.RawURLEncoding

func (Buffer) Bytes ¶

func (b Buffer) Bytes() []byte

Bytes returns the raw bytes that comprises the Buffer

func (Buffer) Len ¶

func (b Buffer) Len() int

Len returns the number of bytes that the Buffer holds

func (Buffer) MarshalJSON ¶

func (b Buffer) MarshalJSON() ([]byte, error)

MarshalJSON marshals the buffer into JSON format after encoding the buffer with base64.RawURLEncoding

func (Buffer) NData ¶

func (b Buffer) NData() []byte

NData returns Datalen || Data, where Datalen is a 32 bit counter for the length of the following data, and Data is the octets that comprise the buffer data

func (*Buffer) UnmarshalJSON ¶

func (b *Buffer) UnmarshalJSON(data []byte) error

UnmarshalJSON unmarshals from a JSON string into a Buffer, after decoding it with base64.RawURLEncoding
