Should be real simple. But adding a small template constraint
causes compile failure. I've got the following working code:
int arrayByteSize(T)(T[] someArray)
{
ubyte[] arr = cast(ubyte[]) someArray;
return arr.length; // length is implicitly converted
to bytes.
}
// running the following code:
GLfloat[] dynamicVerts = [0.0, 1.0,-1.0, -1.0, 1.0, -1.0 ];
int lengthInElements = dynamicVerts.length;
myLog!lengthInElements;
int sizeInBytes = dynamicVerts.arrayByteSize;
myLog!sizeInBytes;
// returns the correct results:
lengthInElements = 6
sizeInBytes = 24
However, when I try to add a simple constraint to the function
like so:
int arrayByteSize(T)(T[] someArray) if (isDynamicArray(T))
{
ubyte[] arr = cast(ubyte[]) someArray;
return arr.length; // length is implicitly converted
to bytes.
}
I get Error: cannot pass type float as a function argument
After I comment out //int sizeInBytes =
arrayByteSize(dynamicVerts);
everything compiles. I've been fighting this for hours. Am I
overlooking the obvious?
