data T ap

track :: (Storable a, MakeValueTuple a, ValueTuple a ~ al, C al) => T p a -> T p Int -> T p al (T (Struct al))

track initial time tracks the last time sample values including the current one. The values before the actual input data are filled with initial. The values can be accessed using index with indices ranging from 0 to time.

The time parameter must be non-negative.

The initial value is also needed for determining the ring buffer element type.

index :: C a => Value Word32 -> T (Struct a) -> CodeGenFunction r a

This function does not check for range violations. If the ring buffer was generated by track initial time, then the minimum index is zero and the maximum index is time.

oldest :: C a => T (Struct a) -> CodeGenFunction r a

Fetch the oldest value in the ring buffer. For the result of track initial time this is equivalent to index time but more efficient.
