pub struct EscapeNullBytes;
Expand description

Escapes null bytes in variable length fields in composite keys. This option ensures proper sort order is maintained even when null bytes are used within vairable fields.

To see more information about the edge case encoding prevents, see CompositeKeyFieldContainsNullByte.
