Module mz_repr::strconv

Routines for converting datum values to and from their string representation.

The functions in this module are tightly related to the variants of ScalarType. Each variant has a pair of functions in this module named parse_VARIANT and format_VARIANT. The type returned by parse functions, and the type accepted by format functions, will be a type that is easily converted into the Datum variant for that type. The functions do not directly convert from Datums to Strings so that the logic can be reused when Datums are not available or desired, as in the pgrepr crate.

The string representations used are exactly the same as the PostgreSQL string representations for the corresponding PostgreSQL type. Deviations should be considered a bug.
