Packed Data Support in Haskell
Packed Data x Haskell = Portable(Type-safety + performance)
This blog post aims to be a short and accessible summary of a paper that will be published at ECOOP 2025, titled Type-safe and portable support for packed data. As far as we are aware, this is on of the first effort to bring support for packed data using only the host language’s type-system, meta-programming (Template Haskell) with no compiler modifications. When building packed data, the library automatically inserts these indirections and modifies the signature of the case function so that its PackedReader know that there are FieldSize interspersed in the buffer.
