Detailed Description

template<typename T>
struct cppfig::ConfigTraits< T >

Primary template for configuration type traits.

Users must specialize this template for custom types to enable serialization, deserialization, and validation. Default specializations are provided for primitive types (int, double, bool, std::string).

Template Parameters

T	The configuration value type.

Member Function Documentation

Deserialize()

template<typename T >

static auto cppfig::ConfigTraits< T >::Deserialize ( const Value &  value ) -> std::optional< T >=delete

staticdelete

Deserializes a value from a Value node.

Parameters

value

The Value node to deserialize.

Returns

The deserialized value, or std::nullopt on failure.

FromString()

template<typename T >

static auto cppfig::ConfigTraits< T >::FromString ( std::string_view  str ) -> std::optional< T >=delete

staticdelete

Parses a value from a string (e.g., from environment variables).

Parameters

str	The string to parse.

Returns

The parsed value, or std::nullopt on failure.

Serialize()

template<typename T >

static auto cppfig::ConfigTraits< T >::Serialize ( const T &  value ) -> Value=delete

staticdelete

Serializes a value to a Value node.

Parameters

value

The value to serialize.

Returns

The Value representation of the value.

ToString()

template<typename T >

static auto cppfig::ConfigTraits< T >::ToString ( const T &  value ) -> std::string=delete

staticdelete

Converts a value to a human-readable string.

Parameters

value

The value to convert.

Returns

String representation of the value.
