Returns
std::string Json built from the structure

◆ fill_from_json()

template<typename T >
template<typename U = T, typename = decltype(std::declval<U&>().fill_from_json_impl(std::declval<nlohmann::json*>()))>

inlineinherited

Convert object from nlohmann::json.

Parameters
jnlohmann::json object
Returns
T& Reference to self for fluent calling

◆ fill_from_json_impl()

emoji& dpp::emoji::fill_from_json_impl ( nlohmann::json *  j)
protected

Read class values from json object.

Parameters
jA json object to read from
Returns
A reference to self

◆ format()

std::string dpp::emoji::format ( ) const

Format to name if unicode, name:id if has id or a:name:id if animated.

Returns
Formatted name for reactions

◆ get_creation_time()

constexpr double dpp::managed::get_creation_time ( ) const
inlineconstexprnoexceptinherited

Get the creation time of this object according to Discord.

Returns
double creation time inferred from the snowflake ID. The minimum possible value is the first second of 2015.

◆ get_mention() [1/2]

std::string dpp::emoji::get_mention ( ) const

Get the mention/ping for the emoji.

Returns
std::string mention

◆ get_mention() [2/2]

static std::string dpp::emoji::get_mention ( std::string_view  name,
snowflake  id,
bool  is_animated = false 
)
static

Create a mentionable emoji.

Parameters
nameThe name of the emoji.
idThe ID of the emoji.
is_animatedis emoji animated.
Returns
std::string The formatted mention of the emoji.
