Overview

Package protohelpers provides helper functions for encoding and decoding protobuf messages. The spec can be found at https://protobuf.dev/programming-guides/encoding/.

	// ErrIntOverflow is returned when decoding a varint representation of an integer that overflows 64 bits.

Functions

func EncodeVarint

func EncodeVarint(dAtA []byte, offset int, v uint64) int

EncodeVarint encodes a uint64 into a varint-encoded byte slice and returns the offset of the encoded value. The provided offset is the offset after the last byte of the encoded value.

func SizeOfVarint

func SizeOfVarint(x uint64) (n int)

SizeOfVarint returns the size of the varint-encoded value.

func SizeOfZigzag

func SizeOfZigzag(x uint64) (n int)

SizeOfZigzag returns the size of the zigzag-encoded value.

func Skip

func Skip(dAtA []byte) (n int, err error)

Skip the first record of the byte slice and return the offset of the next record.
