Module utils

Utilities for encoding and decoding.

Structs

IncompleteBuffer

Returned when the buffer does not contains engouth bytes for decoding.

InsufficientBuffer

Returned when the encoded buffer is too small to hold the bytes format of the types.

Enums

DecodeVarintError

Decoding varint error.
