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.

	ErrUnexpectedEndOfGroup = fmt.Errorf("proto: unexpected end of group")
)

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.
