Member Function Documentation

build_json()

template<typename T >

template<typename U = T, typename = decltype(std::declval<U&>().to_json_impl(bool{}))>

std::string dpp::json_interface< T >::build_json ( bool  with_id = false ) const

inlineinherited

Convert object to json string.

Parameters

with_id

Whether to include the ID or not

Note

Some fields are conditionally filled, do not rely on all fields being present

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*>()))>

T& dpp::json_interface< T >::fill_from_json ( nlohmann::json *  j )

inlineinherited

Convert object from nlohmann::json.

Parameters

j	nlohmann::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

j	A 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

name	The name of the emoji.
id	The ID of the emoji.
is_animated	is emoji animated.

Returns

std::string The formatted mention of the emoji.

get_url()

std::string dpp::emoji::get_url	(	uint16_t	size = 0,
		const image_type	format = i_png,
		bool	prefer_animated = true
	)		const

Get the custom emoji url.

Parameters

size	The size of the emoji in pixels. It can be any power of two between 16 and 4096, otherwise the default sized emoji is returned.
format	The format to use for the emoji. It can be one of i_webp, i_jpg, i_png or i_gif. When passing i_gif, it returns an empty string for non-animated emojis. Consider using the prefer_animated parameter instead.
prefer_animated	Whether you prefer gif format. If true, it'll return gif format whenever the emoji is available as animated.

Returns

std::string emoji url or an empty string, if the id is not set
