ReadonlydigitThe character set used for representing digits in the fractional index.
These characters form the ordered set used to encode the actual index values, and must be in ascending lexicographic order.
The second and all subsequent characters of a fractional index come from this character set.
ReadonlylengthThe character set used for encoding the length of the integer part.
This determines what characters are used to represent the length of the integer portion of the fractional index. Characters must be in ascending lexicographic order.
The first character of a fractional index comes from this character set.
ReadonlytypeThe type discriminator identifying this as a string fractional index configuration.
Base configuration for string-based fractional index implementations.
Defines the configuration for fractional indices represented using string encoding, where indices are stored as human-readable strings using specified character sets.
String indices are useful when human readability or sortability in standard string contexts (like databases) is required.
