Function Documentation

◆ bound_check() [1/3]

constexpr bool hi::v1::bound_check	(	std::integral auto	index,
		bound_check_range_helper auto &&	range )

constexprnoexcept

Check if an index is within a range.

Parameters

index	The index to check.
range	The range object, such as a vector or array, which has a `std::ranges::size()`.

Returns: true If index natural and below the size of the array.

◆ bound_check() [2/3]

constexpr bool hi::v1::bound_check	(	std::integral auto	index,
		std::integral auto	lower,
		std::integral auto	upper )

constexprnoexcept

Check if an index is between the lower (inclusive) and upper (exclusive).

Note: It is undefined behavior when upper is lower than lower.

Parameters

index	The index to check.
upper	The lower bound.
upper	The upper bound.

Returns: true If index is greater or equal to lower bound and index is less than upper bound.

◆ bound_check() [3/3]

constexpr bool hi::v1::bound_check	(	std::unsigned_integral auto	index,
		std::unsigned_integral auto	upper )

constexprnoexcept

Check if an unsigned index is less than the bound.

Parameters

index	The unsigned index to check.
upper	The upper bound.

Returns: true If index is less than the upper bound.

◆ compare_store() [1/2]

template<typename T , typename U >

bool hi::v1::compare_store	(	std::atomic< T > &	lhs,
		U &&	rhs )

noexcept

Compare then store if there was a change.

Note: This atomic version does an lhs.exchange(rhs, std::memory_order_relaxed)

Returns: true if a store was executed.

◆ compare_store() [2/2]

template<typename T , typename U >

bool hi::v1::compare_store	(	T &	lhs,
		U &&	rhs )

noexcept

Compare then store if there was a change.

Returns: true if a store was executed.

◆ fit() [1/2]

aarectangle hi::v1::fit	(	aarectangle const &	bounds,
		aarectangle const &	rectangle )

noexcept

Make a rectangle fit inside bounds.

This algorithm will try to first move the rectangle and resist resizing it.

Parameters

bounds	The bounding box.
rectangle	The rectangle to fit inside the bounds.

Returns: A rectangle that fits inside the bounds

◆ fit() [2/2]

aarectanglei hi::v1::fit	(	aarectanglei const &	bounds,
		aarectanglei const &	rectangle )

noexcept

Make a rectangle fit inside bounds.

This algorithm will try to first move the rectangle and resist resizing it.

Parameters

bounds	The bounding box.
rectangle	The rectangle to fit inside the bounds.

Returns: A rectangle that fits inside the bounds

◆ from_string() [1/2]

template<std::floating_point T>

T hi::v1::from_string ( std::string_view str )

Convert a string to an floating point.

This function bypasses std::locale

Template Parameters

T	The integer type.

Parameters

str	The string is an integer.

Returns: The integer converted from a string.

◆ from_string() [2/2]

template<std::integral T>

T hi::v1::from_string	(	std::string_view	str,
		int	base = 10 )

Convert a string to an integer.

This function bypasses std::locale

noexcept

Get the OS error message from the last error received on this thread.

◆ prepare_debug_break()

void hi::v1::prepare_debug_break ( )

noexcept

Prepare for breaking in the debugger.

This will check if a debugger exists and potentially launch the Just-In-Time debugger if one is configured. This function may terminate the application if no debugger is found.

It does not do the actual breaking.

◆ process_call()

template<typename Functor >

void hi::v1::process_call	(	Functor &&	functor,
		std::string_view	data )

Call a function in a new process.

Parameters

functor	A functor `void(std::string_view)` to call in a different process. You can pass for example a non-capturing lambda
data	Data to pass to the functor.

◆ terminate_handler()

void hi::v1::terminate_handler ( )

noexcept

The HikoGUI terminate handler.

This handler will print an error message on the console or pop-up a dialogue box.

Note: Use hi_set_terminate_message() to set a message.
