Deserialize one entry from data[offset..], setting bytes_read to the bytes it consumed.
Every field is bounds-checked against the entry's own declared length as well as the buffer, so a hostile length can neither read past the buffer nor reach into the entry that follows.
◆ serialize()

◆ serialize_into()
| void librats::StorageEntry::serialize_into |
( |
std::vector< uint8_t > & |
out | ) |
const |
Append the serialized entry to out.
What serialize() is built on: a batch appends entry after entry into one buffer instead of allocating a vector per entry only to copy it away again.
◆ serialized_size()
| size_t librats::StorageEntry::serialized_size |
( |

const |
Serialized size in bytes, without serializing.
