Enumeration Type Documentation

strong

Error codes returned by parse_unit_value / parse_measure_value.

Enumerator
Empty	Input was empty or whitespace-only.
InvalidNumber	Numeric portion failed to parse.
UnknownUnit	Symbol/id not present in the registry.
UnitMismatch	Symbol parsed but doesn't match the requested unit tag.
MeasureMismatch	Measure id doesn't match the requested measure tag.
TrailingGarbage	Unexpected characters after the value.

strong

Error codes for range construction.

Enumerator
MaxLessThanMin	Upper bound is strictly less than lower bound.
EmptyOpenRange	Equal bounds with at least one exclusive side.
