This namespace facilitates unexternalization of all BDEX‐compliant types in a type‐independent manner. The unexternalization functions are overloaded for fundamental types, enumeration types, `bsl::string`, and `bsl::vector`. A compilation error will occur if the (template parameter) `VALUE_TYPE` of a non‐overloaded method of `bslx::InStreamFunctions` does not support `bdexStreamIn` (with the appropriate signature).

| This `struct` provides a namespace for implementation helper functions for this component. They are not intended for use outside this component.
| xref:BloombergLP/bslx/InStreamFunctions/IsEnumType.adoc[`IsEnumType`] 
| This `struct`, together with `IsNotEnumType` (below), is used to distinguish enumeration types from other types in function overload resolution. This `struct` contains no interface or implementation by design, and is meant for internal use only.
