cppfig::ConfigTraits::Deserialize
static auto Deserialize(const Value &value) -> std::optional< T >=delete
Deserializes a value from a Value node.
cppfig::ConfigTraits::ToString
static auto ToString(const T &value) -> std::string=delete
Converts a value to a human-readable string.
cppfig::ConfigTraits::FromString
static auto FromString(std::string_view str) -> std::optional< T >=delete
Parses a value from a string (e.g., from environment variables).
cppfig::ConfigTraits::Serialize
static auto Serialize(const T &value) -> Value=delete
Serializes a value to a Value node.

Detailed Description

Concept constraining types that can be used as configuration values.

A type satisfies Configurable if ConfigTraits<T> provides the required static member functions for serialization and conversion.
