Ptr.Poking

Documentation

data Poking

An efficiently composable unmaterialised specification of how to populate a pointer.

Once composed it can be materialized into a specific data-structure like ByteString or to directly populate a pointer in some low-level API.

Constructors

Poking !Int !(Ptr Word8 -> IO ())

• Amount of bytes the encoded data will occupy.
• Exception-free action, which populates the pointer to the encoded data.
