Detailed Description

Function Documentation

Span<const T, Extent> mbed::make_const_Span ( const T(&)  elements[Extent])

Generate a Span to a const content from a reference to a C/C++ array.

Template Parameters
TType of elements held in elements.
ExtentNumber of items held in elements.
Parameters
elementsThe array viewed.
Returns
The Span to elements.
Note
This helper avoids the typing of template parameter when Span is created 'inline'.

Span< const T, Extent > make_const_Span ( const T *  elements)
related

Generate a Span to a const content from a pointer to a C/C++ array.

Template Parameters
ExtentNumber of items held in elements.
TType of elements held in elements.
Parameters
elementsThe reference to the array viewed.
Returns
The Span to elements.
Note
This helper avoids the typing of template parameter when Span is created 'inline'.

Span< const T > make_const_Span ( T *  array_ptr,
size_t  array_size 
)
related

Generate a Span to a const content from a C/C++ pointer and the size of the array.

Template Parameters
TType of elements held in array_ptr.
Parameters
array_ptrThe pointer to the array to viewed.
array_sizeThe number of T elements in the array.
Returns
The Span to array_ptr with a size of array_size.

Variable Documentation

const ptrdiff_t SPAN_DYNAMIC_EXTENT = -1
