The Conversion Library improves program safety and clarity by performing otherwise messy conversions. It includes cast-style function templates designed to complement the C++ Standard's built-in casts.
To reduce coupling, particularly to standard library IOStreams, the Boost Conversion Library is supplied by several headers:
polymorphic_downcast<>to perform safe casting between polymorphic types.
implicit_cast<>to perform implicit casts only (no down-cast, no void*->T*, no U->T if T has only explicit constructors for U).
lexical_cast<>general literal text conversions, such as an
intrepresented as a
string, or vice-versa.
