Member Typedef Documentation

using modm::Fiber< fiber::StackSizeDefault >::binary_semaphore = counting_semaphore<1>
inherited

Implements the std::binary_semaphore interface for fibers.

https://en.cppreference.com/w/cpp/thread/counting_semaphore
using modm::Fiber< fiber::StackSizeDefault >::id = uintptr_t
inherited

Identifier of a fiber task.

Member Enumeration Documentation

enum modm::Fiber::Start
inheritedstrong

The Fiber scheduling policy.

Member Function Documentation

modm::fiber::id modm::fiber::Task::get_id ( ) const
inheritednodiscardinline

Returns a value of std::thread::id identifying the thread associated with *this.

Note
This function can be called from an interrupt.
bool modm::fiber::Task::isRunning ( ) const
inheritednodiscardinline
Returns
if the fiber is attached to a scheduler.
void modm::fiber::Task::join ( )
inheritedinline

Blocks the current fiber until the fiber identified by *this finishes its execution. Returns immediately if the thread is not joinable.

bool modm::fiber::Task::request_stop ( )
inheritedinline
Note
This function can be called from an interrupt.
size_t modm::fiber::Task::stack_usage ( ) const
inheritednodiscardinline
Returns
the stack usage as measured by a watermark level.
See also
modm_context_stack_usage().
void modm::fiber::Task::stack_watermark ( )
inheritedinline

Watermarks the stack to measure stack_usage() later.

See also
modm_context_stack_watermark().
bool modm::fiber::Task::start ( )
inherited

Adds the task to the currently active scheduler, if not already running.

Returns
if the fiber has been scheduled.

Member Data Documentation

constexpr size_t modm::Fiber< fiber::StackSizeDefault >::StackSizeDefault
inheritedstaticconstexpr

The default stack size is estimated experimentally so that a fiber can use modm::IOStream to log out information, which is fairly stack intensive. Use modm::fiber::Task::stack_usage() to determine the real stack usage.
