Detailed Description

template<typename TYPE>
class original::coroutine::generator< TYPE >

Lazy sequence generator using C++20 coroutines.

Template Parameters

TYPE	Type of values generated by the coroutine

Implements the coroutine promise protocol to create generators that can yield sequences of values. Supports range-based for loops, manual iteration, and exception propagation.

The generator maintains the following states:

• Suspended: Waiting to be resumed (initial and after each yield)
• Running: Currently executing coroutine logic
• Completed: All values have been generated

Note

Generators are move-only types to prevent accidental copying of coroutine state.

Iterators become invalid when the generator is destroyed or moved.

Constructor & Destructor Documentation

generator() [1/2]

template<typename TYPE >

original::coroutine::generator< TYPE >::generator ( generator< TYPE > &&  other )

noexcept

Move constructor transfers coroutine ownership.

Parameters

other

Generator to move from

Note

Source generator becomes empty after move

generator() [2/2]

template<typename TYPE >

original::coroutine::generator< TYPE >::generator ( handle  h )

explicit

Constructs generator from coroutine handle.

Parameters

h	Coroutine handle to manage

~generator()

template<typename TYPE >

original::coroutine::generator< TYPE >::~generator

(

)

Destructor cleans up coroutine resources.

Note

Automatically destroys coroutine handle

Member Function Documentation

begin()

template<typename TYPE >

original::coroutine::generator< TYPE >::iterator original::coroutine::generator< TYPE >::begin

(

)

Gets begin iterator for range-based operations.

Returns

Iterator positioned at first value

Note

Resumes coroutine to get first value

end()

template<typename TYPE >

original::coroutine::generator< TYPE >::iterator original::coroutine::generator< TYPE >::end ( )

static

Gets end iterator for range-based operations.

Returns

End iterator marker

hasNext()

template<typename TYPE >

bool original::coroutine::generator< TYPE >::hasNext

(

)

const

Checks if generator has more values.

Returns

true if next() would return a value

launched()

template<typename TYPE >

bool original::coroutine::generator< TYPE >::launched

(

)

const

Checks if coroutine has been launched.

Returns

true if coroutine has started execution

next()

template<typename TYPE >

original::alternative< TYPE > original::coroutine::generator< TYPE >::next

(

)

Advances generator and gets next value.

Returns

optional containing next value if available

Note

Resumes coroutine execution and may throw exceptions

operator=()

template<typename TYPE >

original::coroutine::generator< TYPE > & original::coroutine::generator< TYPE >::operator= ( generator< TYPE > &&  other )

noexcept

Move assignment operator transfers coroutine ownership.

Parameters

other

Generator to move from

Returns

Reference to this generator

Note

Destroys current coroutine handle before transfer

peek()

template<typename TYPE >

original::alternative< TYPE > original::coroutine::generator< TYPE >::peek

(

)

const

Peeks at current value without advancing.

Returns

optional containing current value if available

Note

Does not resume coroutine or change state
